[TheBluerims]

@kapwc4eva your timing might be off check that

[KAPWC4EVR]

I both cleaned and replaced my air engine valve on my 1992 honda civic dx, but I still have the same reving problem in park. Also I have in the past two months replaced the head gaskett and the timming belt. Any Suggestions?

[MrHoussain]

Hi guys, What's the right number of Matiz II Idle Air Control . My Matiz is model 2000.

[mrlakayna]

despite your accomplishment thanks for taking the time to teach the basic stuff, much appreciated. just what im looking for...

[mrlakayna]

THANKS MATE

[Pamballa010]

THANKS SO MUCH!

[pokerrock]

Thank you for this video I finally cleaned mine today there was gunk all around the circle and a clear middle ,bought some Oreillys carb cleaner and sprayed it and the hole was clean of all the gunk noticed a difference starting and stopping at a stop idling . Thanks .

[hp11208]

cool

[fordxbgtfalcon]

damn! thats a nice accord!

[swclemmons1]

ha leaf boost at 25 secs. love it



[blackericdenice]

Did the same iac valve cleaning to my girl 98 crv no more low idle and her a/c works again. A/c man said she needed $350 a/c service before. BASTER!

[fleckx]

@blackericdenice LOL YUP I was looking up A/C problems like I have, where my A/C only works for a while and then starts cycling on and off, and the RPMs drop heavily when I turn the A/C on. I've had people tell me it was the A/C compressor clutch, the compressor itself is bad, etc. Anyway from my search it turns out it could be (should be) the air idle control valve. I am about to take it out and clean it, ASAP.

[noahkeebler]

whats your opinion on h22? or how about turbo?'



[christianbaclao]

great vid, do you have any videos on how to remove an entire manifold?i have a 91 integra with b20 swap. what kind of intake manifold is that?

[Skittlesking]

I lol'ed at the leaf

[seebukey]

i cleaned mine and put it back on and the car tumbles but won't start....y?

[deediamonds27]

my 93 honda civic (169,000 mi.) shakes a lot when I'm at stopped at a red light, stop sign..etc, i have to put it on neutral so it won shake that much and when i turn the AC it gets worst and the car shuts off.... anyone knows if cleaning the IACV will fix this problem? or what could it be? please help!

[9522369356]

thanks alot man

[alekscooool]

Hey i got a 2000 civic and only when the a/c is on the idle starts jumping so if i do this and clean it will that fix that?

[kyle88l]

yo where did you get your little filter on the valve cover? The engine breather hole or whatever it is called? I have been looking everywhere for one lol

[iceveiled]

Nice video. My 98 civic would idle fine until warm,then it would yo-yo idle from 1000, to 1700 and back down repeat, whenever I was at a stop. Really annoying. Also throwing a CEL. I diagnosed the CEL and it came back with an IACV error. My IACV was gunked up. Cleaned it up and it idles great now. I like your turbo D - the little engine that could.

[eak848]

i cleaned my mitsi lancer evolution 4 one and it wouldn't stop idling high had to replace the hold thing

[DoubleRRHomepage]

lol thts not a junker man the a great car unleess ur comparing it to a porche then still

[am2r]

do we have to replace the gasket?

[nx2overide]

@am2r I didn't but my gasket looked ok.

[brendanholst]

@nx2overide Where do the hoses go that are on the iac . i bought a car thinkin the iac valve was bad but found out that neither of the hoses were on it .

[neo2reo]

fuck today I spent like 5 hours trying to figure out the rought idling , low almost dying when in gear on my 89 lxi honda , finaly I gave up and decided to do some research online got the answer in about 2 minutes through google , what a dumb ass lol , thanks for the vid man , just a little tip for others just in case , look for the intake , throttle body on your vechicle and this piece of shit must be there near it , thanks again man and keep up the good work .

[gavinpj]

Does a 1996 1.6 non vtec have the same thing? My car idles normal then idles down to around 700rpm

[iceveiled]

@gavinpj 700 +/- 50 is normal for your D16.

[Vietwhiteboy]

Thanks for this video I finally got time to clean mine WOW much much better idle. On mine that metal mesh filter on the IACV was dirty as hell.

[Chewy502]

lol i acutally cleaned mine a few days ago.. i also have a 93 civic coup everytime i started the car it would idle up and down for about a min or so then stop

[Vietwhiteboy]

Thanks for the video it was well done. Mine has low idle and it has new air filter, sparks plugs, o2 sensor, basically all tuned up just idles low. My alternator and fuel pump is really old so they might be next thing replaced also. If cleaning the IACV doesn't work.

[MrMistermister101]

is your eg your dd?

[PRZJ91]

so how far have you come since then.....are you an engine guru?

[nx2overide]

@PRZJ91 LOL i wouldn't say guru but yes i have done a couple turbo mods and swaps with friends. Fun Fun. Been planning for my other civic but I got to get the funds together to do the swap. I want to go B16 Swap with a stage 5 turbo kit. I already have a new fly wheel and trany ready i just got to crate the engine and get the turbo kit.

[PRZJ91]

@nx2overide niiiice.....im headin off to UTI in august and hopefully gonna fulfill my dream with pursuing cars.......its good to see you doing well bro......keep it up

[sammy589]

It can also be located on the front of your intake manifold. After cleaning the IACV its also really good to clean the valve inside it where more build-up is located.

[KaysinUSA]

I suggest if you are having this problem, get it fixed ASAP.. don't wait like I did lol. Actually got rear-ended because my car stalled out making a right hand turn at a stoplight. 2500$ later the damages are repaired, could have saved myself a huge headache.

[dzld9]

Thanks for the tip on how to clean the iacv and for the people that can't find their iacv it is generally right next to or near your throttle!

[SCBianchi]

This is just a good thing to do on your 'major overheal tune-up' routinely

[Dluniz09]

i cant seem to find my IACV on my 93 ford escort LX wagon...it has the 19L EFI

[datrumakboy1020]

i got a 97 taurus sho and to clean it i got it completely off, is all i do is just spray the carb cleaner in there?

[jawsrock1]

Thanks for posting this. I bought a '96 civic and it's having simular problems. This is a great video to show me what the problem could be and how to fix it. Thanks.

[TheFailnoob]

Is the IACV valve the same as an EGR(exhaust gas recirculation) valve or are they two separate parts on most cars? I have a 1994 s10 blazer.

[AIERBIZ]

Thanks, I was going to disasemble the thing it is so black inside. But I can't find the right torx or allen bit.

[smithraymond09029]

I always take car adivce from a guy that looks like he lives in an Appalachian mountain shack.

[Dpman3690]

ur just trying to show off that monster u have under the hood

[reyrey7777]

Can anyone give me any ideas? I have a 87' honda accord and the idle still surges after i cleaned the idle control valve...it doesnt surge constantly but will surge if the engine is cold or hot....ant ideas will help.....thanks

[TheJoeywinter]

@reyrey7777

my car did this for a while. it was a loose nut on the downpipe area connecting to the header, if theres any leak in your vacumme intake, exhaust wherever it does this.

[Sproy123]

Sometimes when i start my car, espcialy in the mornings or on cold days as well as really hot days, my idle will stick somtimes at 2000 RPMs or a littler lower but will Eventualy die down, do u think it might be the ( IACV) i would really like someones help! haha get back to me if u know anything?

[nx2overide]

@TheSavannahlewis Its most likley located in the same place.. they look the same on hondas so you should be able to find it pretty easy, and yes it can cause a car to stall. glad i could help!

[speedymcfastpants]

i wish i had a supra but i love my eg its a 92 straight junker my wife hates but i love it!!! eg 4 life!!

[crammage]

old civics are better than newer civics

[DiagnosticDDT]

check out enginemisfire,com for care repair

[pokerrock]

Question I have a 1995 civic DX ,it starts fine ,drives fine after starting but if I come to a stoplight and idle it sounds like its going to die but doesnt it seems to just occur in mornings particulary on cold mornings it drives fine and idles fine when I drive back home from work would this solve my problem ?? thanks

[TrollLuv]

@pokerrock hey a real car like a dsm or supra trust me u willnever go back to a honda ever again

[nicknintytwo]

@pokerrock ya i have a 97 civic hx and it only does that at lights also but only when the car is in driveand reverse, if i put it in park or neutral it idles fine any help if you figured out anything. be very helpful

[pokerrock]

@nicknintytwo tuned it up doesnt do it anymore . But while idling only in the morning you hear a pause sometimes in the engine but its fine as soon as I warm it up and drive it now. I just want to probably do this on the video cuz it does have 189k miles on it.

[dtkrob]

Thanks for the vid bro

[delacerdaa]

i just had mine replaced on my 92` lesabre  for $140 w/ labor

[blaza4200]

@delacerdaa u got rape my friend lol took me 10 mins to take this off of my car

[nx2overide]

@blaza4200 yep.. he got bent over on that one... 50 bux for a "new" one for my car and 10 to 15 mins to replace.

[delacerdaa]

@delacerdaa Yeah......but I don`t know mechanics nor do I have the tools. I wish I did......I`m going to start buying tools now that all these mechanic videos are on you tube.

[nx2overide]

@delacerdaa dont feel bad i got slammed many time before I decided not to trust others and do my own work.. i know its done right and not half assed. The internet helps alot i learned everything from videos and forums.

[Sorman26]

Hello, first of all, nice video.  I am from WI and when it gets cold, my 99 Acura TL 3.2 idles poorly when I first start up. Would your video be relevant to my Acura? The sypmtoms are very similar. Any tips or suggestions would definitely help. Thanks in advance.

[DiAbOLiCPeNtaToNiC]

BOOOOOOOSSSSSTTTT!!!!

[axenz1]

Thanks for the info... try to shave and cut long hair... you will be handsome hehe

[cingirpar]

I have a 1999 accord that boggs out a little when you first start it, and when it idles I can feel it hesitating. . would cleaning the iacv help me out??

[DocG4007]

Great vid, however my IAC is on the front of my intake. I'll be using your other vid (I believe) on cleaning the FITV.

Hope to cure my rolling idle.

[rickymac415]

Dooooode, my "92" Prelude was totally fluctuating up and down when it was warming up and I watched your video and then did it to my car and now it runs perfect, Thanx Man you are Awesome !!!!!!!!

[rickymac415]

Dooooode, my "92" Prelude was totally fluctuating up and down when it was warming up and I watched your video and then did it to my car and now it runs perfect, Thanx Man you are Awesome !!!!!!!!

[00Johnny00batten00]

thanks



[383dart383]

Great video i did everything that you showed but i had to relearn my idle to get it back to normal. thanks!

[Sandeep9201]

BOOSTED!! Sick man.

[jeabreg]

It's very important to get to work

[tamaninja00]

What's Charlie Manson doing out of prison?

[Warhawke08]

I have the same car as you, its a 94 but its the same color, very few purple civics out there lol

[nx2overide]

@Warhawke08 rock on! yep it was purple but who ever had it before me painted the car black.. looks more brown though, They didnt paint the jams or engine compartment..lol

[tbone912]

awesome dude, step one to fixing my car's(93 civic FTW) rough idle

[grcain]

Great Video dude! Thanks for the help!

[fefo360]

does a dirty IACV can cause car vibration when idle?

[rangie1625kaidrian]

its a “must” to replacement but it's quite expensive parts for Honda!... it will cause about $250 around that price!!! but it's worth it and it will last for a long period of time to replace it again!... if you clean it you'll have the same problem over and over again! just for a few days it will come back! so the best thing to do is replace the parts!...

[virtualwebman]

I cleaned out my 97 Honda civic 214,000 miles on it with seafoam and now it started to idle up and down.

Do you think debris could have got into the IACV? I may try to clean it tomorrow.

[yamahaua]

good video . hope to help me and a friend of mine . both we have idle problems with hondas

[jbentley8383]

I got low idle on my car and people been saying it might be my IACV and to clean it...BUT they never never never never say how to do it or where it is.

That's when i saw this video..just wanted to thank you! I got a 92 civic that I use as work car but it stalls all the time so it's not going anywhere but cleaning the IACV is a start on finding out what's wrong with my car.

[nick1c1]

HONDAS ROCK!!!

[NacionaL305]

hey man nice vid. got one question- randomly at the beginning of my drive my car seems to choke. im cruising going thru gears when out of nowhere my seems to be dying down. i give it gas and nothing until i give it enough or get to 3k and it shoot out. if i put it in neutral or stop it boggs down to maybe 200rpm then idles back to 800. i cleaned the iacv and still have the problem. any suggestions?

[loverboygnd]

nice ride bro, nice boost setup, definitely not a junker, props on the vid

[EveningGoDs]

Thanks bro

[muzicguru]

I'm having problems with my idle but i'm not exactly mechanically minded. Anyone know where id be able to find out where the IACV is on a 1992 primera?

[Ad7jdm]

nice civic nice turbo set up too

[doubledensity]

Nice EG, it doesnt look like a junker... your car looks clean... thanks for the vid.. this helped my erratic idle while my a/c is on... =)

[adrianTNT]

0:08 Boo !!! you scared me :)

[DMdrumma138]

doesnt look like a junker to me,nice civic!!

[blowcoke]

my car does serges so i need to replace it or would cleaning it werk

[stutteral]

hey! this was a great vid :) I have a problem with my car as well, But it seems to jump rpm's ???? and at cold start it will not stay started at all unless i warm it up??? any ideas?? I have a 1994 honda civic turbo coupe 1.5L w a obx intake manifold. I was told to replace the throttle cable with a 1995 acura gsr To fix the problem? It just doesn't sound right?? if you can txt me plz do 719-778-2873 thanks

[jimnel1]

Nice Video. It's was very helpful .

[sparkscarz]

thanks dude this helped!!

[1empyre]

Nice video. I'm not sure if this has been said, but you might consider leaving the parts on longer. I read fast enough, and had to go back and pause it every time a text frame came along. The video helped, even though I have a Toyota!

[nx2overide]

right on!! ohh and thanks i will keep that in mind on my next car video.

[arkomandos]

yo man I also have a civic hatch 94,,with a little t25 on it,I had my ecu tuned,,,this time the knock sensor is off,,and also the launch control is set,,,it did not have those 2 before,and its not always but sometimes when I turn the car it will idle low,,,and sometimes is idles normally,,its like 50/50,is there some kind of a trick with the ignition,like to turn the key over without the clutch so it resets something? cause I dont know man,or is this caused mainly by the knock sensor,

[arkomandos]

nvm,,,I got it,,,well it turns out to be a bad tune,,,I had a full before but,,,I had the car stolen and the ecu with it,,,,so I got a basic crome tune,,,,,,I swapped another tuned ecu from a different car just to see how is it,,,,,,, and it worked perfect,,,,well will probably get a full tune after the winter because I will not drive the car in the winter,,,,peace

[jutsze]

civics arent junker theyll be the future classic bro. hondas were made for speed man speed..speed man...

[bOk8]

hey man is it applicable if my problem is when i turn on the a/c my idling keeps on going up & down?

[kazanyemmi]

hey man, Im pretty sure the problem with my car is my IACV. was your honda having alot of up and down rev'ing? mine is doing it alot and I have videos of it on my youtube account. Im trying to see if its easier to clean it then replacing it. which is how I came across your video.

I just wanted to see if you were having the same issues I was- and that cleaning would be my first bet at fixing it? comment back or send me a message (if you could, message me I notice it easier haha)

[tre08748]

aye bro i gotta 95civic dx and my lights flicker with the engine and i have a low idle if u need i could post a vid so u could see what i am talking about how can i fix this prob ?

[bmxjosh25]

hey i got a 96 honda civic dx with the 16 valve and i just cleaned my iacv and i still have the rough idle what else can it be?? im guna look it over tomaorw and see if i have any vacum leaks. but any sugtions on what else it can be?? thanks

[nx2overide]

you could try cleaning your FITV (Fast Idle Thermo Valve)

[bmxjosh25]

i did a intake leak by taking the air filter off and i tryed to stall it well it didnt stall. it sounded like it was sucking air under my tb(throttle body). bad tb gasget maybe??

[nx2overide]

@bmxjosh25 sounds like it... id replace it and try again to see it you can get it to stall.

[HarleyStcool]

96 and up don't got fitv's brah, its just 95 and down, thats why iacv's are the most common problem. What kind of idle does it have? up and down idle ( fast )? or is it just a rough idle in general?

[HarleyStcool]

hey brah just a quick qustion, those two hoses are filled with coolant right? i got a honda civic 1990, i was just worrying that if i pull them two out that my coolant will drain out, i'm abit cheap i guess. Can i just clean the iacv without unhooking the hoses?

[nx2overide]

you will only lose a tiny bit it shouldnt drain.

[HarleyStcool]

Thanks! And honda civics are nice

[diavolo803]

lol Nice ride we should line them up..

[vtcftw]

I cleaned the IACV correctly and extensively.

i also put silicone around all the seals incase it's due to a vacum leak. (both IACV & FICV)

AND look the throttle body off and cleaned that (all the gallies and pasages)

still experiencing the fluctuations at operating temp.... Think maybe replace the IACV all together incase it's due to the electrical side of it?

[nx2overide]

weird.. yep could be a bad iacv let me know what you find thats odd.

[vtcftw]

Darn!

I cleaned my FICV... will clean the IACV in the morning.

your thoughts on adjusting the "idle adjust screw"?

Nice car, i have an ej1

[nx2overide]

I wouldn't mess with the idle screw unless the car is idling so low it stalls. after you get the Fluctuating idle stabilized then you can adjust it.

Yep i need to clean the FICV on my other civic. i will probably make a video on that too.

Thanks hope it helps.

[scottklaw]

I just love this time of year. It get cold and it time for me to work on my truck and car. Again.

[nx2overide]

me too.. :)

[DrLuis08]

Your car sounds very nice.

[rickyshore]

entertaining and informative, awesome! you seem like an expert.

[nx2overide]

im no expert i just figure things out and tinker on Hondaz.

[OceanTownPictures]

Dude! I tried soooo hard to come up with a creative response to this video but, I am such a mechanical dumbass there is nothing I can say except, I like watching your videos, even if the content goes so far over my head it might as well be a rocket to the moon! lol

[nx2overide]

LOL i was just bored and figured half my viewers would be like what the hell? Hes a mechanic too..lol I just tinker and figured it may help someone as i look for videos like this when i cant figure something out. If it helps one person it was worth uploading.

[sirbobis]

i think you should shoow that damn car morre dude

[TheDarkVII]

Nice car bro!

[nx2overide]

Thanks its my get to work car.

[pianomanIN2009]

haha jack of all trades

[nx2overide]

hey i try. thanks man!

[aROARahVyePer]

5 stars for car instructional video! I know nothing about car engines! :-)

[thehilitereel]

My dad has been working on Honda's ever since they came into the country.

Scooter technology at its best!

[nx2overide]

very cool.. i love hondas cause they are easy to work on. you are correct.

[blackcat2enterprises]

:D I like this one. Would not mind seeing more like this. *grin*

I have a junker too but they are more fun for sure. =)
