Well now im at a loss. my car for the past 2 months has been randomly idling high, i haved replaced the TPS and the MAF LIM and the UIM and it still has a high idle the i replaced the IAC 2 years ago and it seems to be working, i only say this because the car is not at a constant high idle it will come back down after a few seconds or minutes... My friends thinks it has somthing to do with the 160 tstat i put in my car about a year ago he said it might be kicking into open loop or also the EGR could be getting stuck open..
i was wondering if anyone had any ideas?
i was thinking bad TPS or a bad PCM
the tps i bought was a non adjustable from autozone and im sure it was a cardoom so im gonna have to test it the hard way being no scanner will read my car but the paperclip and flashing codes still works
oh and i dont have any codes saved if that helps..

How long since the throttle body has been cleaned? Maybe the throttle plate is gunked up and occasionally sticking open? Some other things to check include: vacuum leaks, PCM ground, fuel in FPR hose, PCV valve.

does it do it when the car is at normal operating temp. or just at start-up?

normal op temp

if thats the case, i would suggest as bill has, to clean the throttle body and sensors.

Get a new TB gasket (may be dealer only for you), and follow the TB/MAF cleaning Techinfo article.

i parts washed my TB last time it was off which was 2 months ago

what did you use to clean the MAF?

TB cleaner then it was making it throw codes so then i cleaned it with brake cleaner
btw my abs quit working today i love my 93 money pit

thats your problem, you NEVER want to use something that aggressive on the maf. i have a couple extras that should work for you. can you post your oe # stamped on the part.
