Replace an EGR Valve : Unhooking an EGR Valve

[grnwood87]

haha ye take off the big nut on the egr valve..not the side connected to the manifold... i learned that the hard way now i gotta buy a new damn egr tube... ugh haha

[Ali3970]

i have an 89 lincoln town car and everytime i hook up my vacumm line onto the nipple of the EGR valve the engine hesitates and then shuts off, can anyone tell me why! please!

[olli3j]

@Ali3970 im having the same problem but with my sierra the rpm runs steady at idle then jumps up and down.. feels like itll stall on me at any time and its runns like its singing the blues.

[mascobe]

I had an EGR valve that went bad but did not cause idle problems; It only caused trouble with light throttle (surging and bucking). Wide open throttle and idle were normal. Pulling and plugging the vacuum line proved nothing, still did the surging thing. Symptoms didn't happen until closed loop operation. I now recomend replacing the EGR when people bring me vehicles with strange surging symptoms and everything else looks good (i.e. the injector spray is consistant and the timing is correct.)

[stgrenade64]

nice vid. now my problem is how to easily disable EGR . do I only have to pull and disconnect the vacuume hose to disable it? i heard it add extra power disabling it.

[JohnUnit]

@stgrenade64 it does not add any extra power. You will lose some fuel economy, too. The only performance benefit is the very slight weight reduction. EGR is not active during full-throttle.

i change the dpfe sensor stay check engine light p401 i put new egr valve new egr valve gasket new new egr valve sensor i think i got carbon build that check engine to stay on oh well

[youpaynow78]

i put new vaccum line and new egr valve and new egr gASKET new fuel rail gasket full tune up new fuel filter new maf still check engine light on for p401 i put new egr sensor both of them run perfect it just light look at it :( im i got carbon despoit left side exhaust mainfold

[CarlosMerighe]

@youpaynow78 , DPFE sensor?

[TehKazangsta]

@youpaynow78 usually check engine lights stay on even after the error was taken care of. you have to hook it up to a obd computer and delete the error message.

[sugahface]

it looks like its freezing in there

[crazylemon101]

guys you guys are sooo immature..

[asada23]

nuts and nipples...mechanics have all the fun!

[journeyquest1]

Cresant wrench? Why not use the correct long pattern combination wrench? I guess cresant is a last resort?

[scottyprimetime]

hahaha!!! He said big nut.

[popopopopopo8]

hahaha!! He said nipple

[SHANGRALAAAA17]

he said large nut and nipple!

[SHANGRALAAAA17]

HAHAHAHHA

[x79datsonx]

This is the only clip where it looks like he knows something.

[04mustangsvtcobra]

thats gonna cost you some money to get that fixed too. it takes a few days too so you better have a backup car

[bryanharricharan]

What will happen if i dont change my egr ??

[04mustangsvtcobra]

youll get very jumpy accelerations, your cars idle will be rough, and your emissions will be affected. usually youll get a engine service warning, so all you have to do is take your car to autozone and have them do a free OBD2 reading to see if thats the problem. most people have never heard of an EGR valve so they wouldnt know what it is or what to do.

[bryanharricharan]

the problem is that Autozone would not check my car because the engine light is off. But the car shaking like if going to install. But never install i dont know what is the problem? Any suggest??

[04mustangsvtcobra]

has to be your transmission if it feels like its going to stall. do you hear like a chatter sound when its shaking or any sound at all. what car do you have first of all? and if its shaking it has to be with the drivetrain(engine, transmission, etc.)

[bryanharricharan]

yes i hear like chatter sound but sometime it do it loud and sometime not much at all. and also when i turn on the A/C or the light at night or up a window up or down the battery point that is low. It got a new alternator and a battery. I got a 1999 Ford Explorer XLT . Any suggest??????

[04mustangsvtcobra]

did the low battery thing get fixed when you got a new battery and alternator? that chatter is either grinding gears, your throw out bearing is bad, or you need to have your clutch disks replaced since its an automatic. i have a very big suspicion that your transmission is bad and you need it replaced or repaired. also, does your battery thing get low when you lower or raise your windows?

[bryanharricharan]

No it continue shaking even with the new battery and the new alternator. I know i got a bad wheel bearing on my driver side wheel. but i dont that is the problem. yes when i raise the window the battery get low. But the tranmission is shift good the only problem with the tranmission is sometime it take like a second longer to get revese. I change the filter on the tranmission and oil too like 3 month ago. What make say that my tranmission is bad?????

[04mustangsvtcobra]

if theres chatter, and the cars shaking, and it seems like its going to stall, it is the drivetrain. nothing electrical can make that happen. unless theres not enough electrical power going to your spark plugs. you should get your distributor checked out, along with your spark plugs and your spark plug wires.

[bryanharricharan]

Because when the engine is cold in the morning only. The car work fine no shaking even when i put a window the battery stay in the middler. The shaking began when is warming up. I means you can see the engine shaking sometime it get worst and sometime not that munch. I put a glass of water on top of the engine in you could see the water moving shaking.

[04mustangsvtcobra]

oh okay, i thought it was when you were driving. its something that internal that isint balanced. it could be a blown piston, your crankshaft isint balanced anymore, misfiring. its with your engine then not your transmission. i kept thinking it was happening when you were driving, but it does it when the engine is warming up.

[bryanharricharan]

Yes you got it so it might be a blown piston or crankshaft you say okay.

[therockkkkher]

bryanharrichran, did you find out what was the problem with your 1999 ford explorer xlt?

[bryanharricharan]

No I couln"t fix cause nobody know what was causing the problem. You know Please tell me thanks,

[therockkkkher]

na, if i did id help ya but i got a similar problem with my ford f250 but its been sitting so long i think the fuel injectors are clogged and its shaking from lack of fuel to the chamber, what did you do with your explorer?

[therockkkkher]

alright, take care, i would have liked to know what it was myself, i was hoping you found out from a mechanic, anyways thanks

[bryanharricharan]

You can try Sea form product to see if it work, good luck

[therockkkkher]

yeah ive heard about that sea foam, havent tried it yet, i used to use gumout complete fuel system cleaner but everyone says the sea foam is best, have you ever tried it?
