ive got a 93 olds cutlass supreme, v6 3.1, when i turn my car on, hot or cold, doesnt matter if ive been drivin it for a while or not, my car starts idling and like 1.25 than it starts shooting up to 2 and 2.5 rpms....my service engine soon light comes on, but flashes no codes, ive got obd 1, if i get in my car and start it, and put it right in drive or reverse, it doesnt shoot up in rpms, im not sure whats goin on, oh the car does drive fine and everything, just this problem, thats bout all

check for vacuum leak, if not then its the IAC, may want to clean it. Then do the idle relearn. This happened to me too. I followed a different relearn then that in the faq.

 

Disconnect battery, reconnect ~30 sec later, start car and let run until warmed up and run for another 5 mins, shut off for 10-20 sec, restart until fans come on. Done.

 

If its still idling high, use carb cleaner to check for vacuum leak.
