Could this be because the car is running to rich or the fact that there is no Cat on my exhaust yet neither is there an O2 sensor? It only happens when the car warms up. Does not happen on startup or when i let the car cool down.

Thanks for the help guys...

Fixed the vacuum leak corner 3 baby

Do a search on here for FITV. Same thing was happening to my 94 Integra. The idle would fluctuate from 1000-2500.

 

I have a similar problem... the cold idle is fine, its only when it warms up... my tac bounces up and down between 500-1000 RPMs... usually not more... tac also bounces when wheel is turned (power steering engages) and if I rev it up, it'll drop to about normal and start bouncing again... if it's just sitting it is usually pretty consistent... still some drop though.... bounces down, back up, then not as far back down again and back up... its WEIRD... ran an induction cleaning service, some injector cleaner, replaced the whole Dizzy... my mechanic seems to think it could be my idle controller.... it needs to be cleaned... but it's buried way down in the bay...

do these symptoms sound familiar?

 

Try the FITV. Its really easy to check. I dont feel like typing out what all is involved but its been covered on here a lot.

 

FITV is cold idle only i believe???

does my 95 GSR even HAVE an FITV?

 

i had this problem with my accord...did a tune up and everything was fine!

 

my problem or the 1k-2.5k idle problem??

 

OOOOooooOO dose your tach just jump up and down?..or dose the idle fluctate?..your RPM'S fluctuate then its either.

1. IAC (IDLE ARE CONTROL VALVE)
2. TPS (THROTTLE POSITION SENSOR)

 

My car would do this cold or warm. I tightened up the fitv and it stopped it.

 

my idle would fluctuate... when i turn the wheel (stopped, not moving), when i would rev it up... it would fall back down and bob up and down, gradually stopping... or when its just sitting (warm) it does the bob up and down every so often...

 

u should post model car you have and year.
i think there are no fitv on obd2, correct me if i'm wrong

yeah its either IAC or TPS....iono but with my luck i had this twice...and both times were TPS but yours could be IAC...but if i had to choose i would say TPS is bad...not a hard fix...just a cost a bitch to buy.

 

i can get parts wholesale... and do the labor myself... what do TPS and IAC stand for??? are they sensors??

 

yes...IAC (IDLE AIR CONTROL) TPS (THROTTLE POSITION SENSOR....it could be FITV too

 

yeah!!!! I THINK ITS FITV VALVE!!!! NOW THAT I THINK OF IT........I GOT IT MIXED UP WITH TPS FOR SOME ODD REASON LOL!

 

Im telling you before you go out and spend money on parts check the FITV first. Its a free fix if thats the case!!

 

im almost certain its ur fitv..96 and up intake mannys do NOT have the fitv..but u have a 95...check it...and tighten it back up..easy fix

 

tighten it back up eh?? and that will take care of it?? I'll have to ask my pop about it, he'll know what it is/what to do... thx all..

 

Here is the thread that shows you where it is and what to do. Now if you use a rachet with a screw driver bit instead of a regular screwdriver to take the cover off the FITV you dont need to take the entire assembly off. Just get the cover off and I used a thin 1" wide file to screw the plastic piece back down. Make sure its all the way down too or itll come loose again.

had the same prob. i replaced my IAC and MAP. runs fine now.

 

good info... keep i t coming fellas!

 

i dunno if u found the problem but check these things in order...

any loose vacuum hoses
EAICV (electronic air idle control valve)
map sensor

i had the same problem and it was #1 for me, but that is what i was told to check in order.

Good luck

 

so this problem could not happen because of the o2 sensor on the exhaust. The computer is not throwing codes so ill check what you guys told me to thanks for the imput...
