Car doesn't idle right...

[grrrrrrr]

My idle is a little high... I've tried adjusting the IAC screw and I looked for vacuum leaks, there were none... I used carb cleaner to look for the vacuum leaks... What else is could it be?

please specify ''a little high"

Could be the IAC on your throttle body. I had my idle stuck at close to 2000 rpms till I figured that one out, but I hope your idle is not THAT high. btw, super302, can you send some pics of the yellow GT for sale to [email protected]. I have a friend who is looking for a good 94/95. Sorry to highjack the thread, but hope the suggestion helps.

Sorry to be so vague... My idle isn't THAT high... just about 100 to 200 rpms up. I adjusted the IAC, that doesn't help, and the little needle that adjusts the physical setting of the throttle valve is all the way up (throttle all the way closed) Hope that helps...

bump the fuel pressure down

sounds like the screw that opens the TB butterfly is holding it open just a hair..........just a thought.......if you didn't install the cam, the previous owner prolly raised the idle to counteract the awful lope of that cam.....lol

I love the lope of my cam, and I installed it... and the idle just recently started doing this, not sure what it is...

if the o2 sensor is still reading lean it will try to accomidateby adding more fuel ... upping idle

bump the fuel pressure down

wouldnt that just be a temporary fix since the EEC will learn around it? Like black945.0 said, it might be in the o2 sensors and why its reading rich...so try some new sensors if the ones u have are old...if not maybe a tweecer to tune it.

Are all the parts/sensors on the throttle body clean?

Good Luck

There is a small set screw on the driver's side of the throttle body. Is that what you have been adjusting? If so, make sure that set screw is turned all the way clockwise. If you cant find anything else and the idle is not over 1000rpms then dont worry about it.
