Idle stays high after driving
My 96 2.3L runs great but randomly when I come to a stop after driving I notice the idle is high. Prob. around 2000 rpms or more. Then later I come to a stop and it is idleing normaly. If its idleing high I can shut off the truck and restart and the idle will return to normal. I did a quick search and It looks others have had problems with their IAC being dirty, I took mine out and it looks rather clean.
Any suggestions on what it could be?
