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?
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 jermy82@hotmail.com. 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...
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
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?
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.
