my 98 integra does the same thing go to my videos and itll show you what mine is doing after it warms up it drops to 1000 rpm but if u rev it itll go back up to about 2000 rpm then go back down
weird mine did this a little while after i adjusted the base idle (i have a 1990 btw) and i just adjusted it again and it stopped, i think on mine the screw comes loose from vibrations and doesnt know whats going on but after adjusting it goes back to normal. good to see im not the only one who had this issue but lol
Just locate the Fast Idle Control Valve - check the service manual for the location (FICV) unscrew the cap and then with a coin screw the plastic part all the way down........
look dude if u havent figured it out yet and still need help its the idle control sensor check the back of you trottle body theres a plug unhook it ,it wont hurt the car cuz i hav a 95 tacoma and a 95 prelude and both went bad so i unhook it and havent had a problem since hope it helps
Mine does that when i first start it up. It runs at about 2500rpm for maybe 30 seconds then does that revving up and down from 1500 to 2000 for maybe a minute. When it warms up its ok. I feel like a right asshole if i end up next to someone at the lights when its going on! :P
its the mass air flow or the throttle position sensor....my car does the same thing....i added a spacer on it then it started doin that but chances or its that
a spacer is atteched to the throttle body and the intake manifold...just increases the air flow somewhat by adding length to the throttle body hince more air flow on to it
catnipfever22 so do you what this promlem is cause i have the idetical proble from 1500 to 2000 it up and down up and down it last a while when its finsh it the needle stays low not on the 1 but the line below am thinking of get a new engine how much for an ls 1990
Mine did that. it ran out of coolant and as soon as i put some in it stopped. dunno if its the same as you but you could try that. was pretty stupid of me not to keep the coolant up but i was pretty new to cars back then.
u either put mad cams in it or you took off the emissions stuff. or mine did that because i have a 5 speed stick and tried puttin an intake on from an automatic
lol, its got toda cams in it!!! haha nawwt, jsut playin.. to be honest, i got no idea wat that is. good luck with it though, ive always wanned to own a first gen integra...
lol the car is 21 years old... who cares. my 88 RS idles at like 600-650 when warmed up and sounds like an old chevy with a cam. gets 35 mpg and is fun as hell, so I could care less!
the reason why its idling like that is because you have air in the raditor system you would need to warm the car up and lossen the plug near or under your intake mainfold and when you loosen it it will be spitting you'll have to make it not spit in away
it's actually called fast idle valve(FIV) and when the plastic nut inside the FIV comes unscrewed you get the bouncy idle problem. you need to open it and re-assemble it and that fixes it.
locations:
88-91 prelude-back of the intake manifold
92-01 prelude-under the throttel body
94-01 integra-under the throttle body
they all have 2 little coolant hoses attached to them. other hondas/acura are similiar in location.
Clean out your IACV on the back of your intake manifold, its 2 12mm bolts. If you look into the 2nd hole there is a small worm gear, spray into that with carb/break cleaner, then blow it out and allow it to dry. You may have to do this several times, but you will eventually see the little gear get clean. It will probably fix your problem, other wise you have a vaccum leak.
Below the throttle body, There is a piece that has rad. hoses going into it. Take it off when the car is cold. On the back take off the two screws, dont LOSE! and tighten the white plug till it gets snug. Replace and dont over tighten the bolts that hold it to the car, 12mm I thinks. It is wax from what ive heard, when it warms it lowers the warming idle. But tightening will over ride and stop the bad idle. This comes from 3 years exp. on a 2nd gen. Many web site forums discuss this. GLHF
hey, question. I have a 95 ls, and its misfiring only after the engine has warmed up and i give her over 1/4 throttle. Ive allready changed the spark plugs, spark plug wires, distributor cap, rotor, coil, and fuel filter. any ideas on what could be causing a misfire?
...most probably caused by rampods....typical honda's.... trust me turn the idle screw down, and drive around, if its too low, adjsut a touch higher, etc....
HOW THE FUCK CAN IT BE A TRANNY AND ENGINE SNOOPY...YOU DUMB FUCKING IDIOT... JUST THINKABOUT WHAT YOU WROTE YOU LOST CUNT! try turning down the idling screw that is positioned on the throttle body.... that will fix the problem....you probably have too much air flowing through the throttle body.....
Replacing the EACV fixed the problem. I replaced it over 4 months ago, and the problem has not reoccurred. Thanks for all the attempts to help, but I actually already understood the cause of the problem, and very clearly explained it in a comment 6 months ago.
thats what happened to my friends 96 integra, " supersized " every thing, except the cans or cams, something like that, any way, it just stalls. so yea, all tho, the sound gets really nice aroun 4 thosand rpm, sound great!! sucks for you tho, good luck!
common problem check fast idle thermo valve , ecu , idle air control valve , the most possible 1 is fast idle thermo valve tho ... haynes manual ! .. good luck
It does seem to be a fairly common problem. The solution to the problem is generally either 1) replace the EICV (electronic idle control valve) or 2) repair a vacuum leak (vacuum leaks can occur in many places, including maladjusted throttle cable, broken vacuum hose, various gaskets).
The problem is that too much air is being allowed into the engine. On most cars, it would just cause the idle to stay high. However, with the gen1 Integra engines, if the throttle is closed and the engine is warmed up, the injectors stop opening if the RPM is above 1200 rpm. This is because the ECU thinks you are decelerating and shuts off the injectors to save fuel. When the RPMs drop back down, the injectors kick in again and the idle rises again, and the oscillations continue. Neat, eh?
my 98 integra does the same thing go to my videos and itll show you what mine is doing after it warms up it drops to 1000 rpm but if u rev it itll go back up to about 2000 rpm then go back down

Mines doing the same thing. It's more than likely the idle air control valve. Try cleaning it out. If that doesnt work, it needs replaced.
