Idle Issues

[Desert Bob]

My 1995 YJ 2.5L has issues at idle. It runs well but it idles rough (kind of pulses) and when started when it is warm it idles high (1500rpms). As soon as I drive off the idle drops down to normal (750-800 rpms). When it is cold it acts like it is going to stall out (but never does). I cleaned the throttle body, IAC and passage and ran some injector cleaner (sea foam) through it but is still acts exaclty the same. Is this the TPS or IAC that controls this circut? The Jeep has 163,000 miles and to my knowledge neither of these have been changed.

give Freewaydan a shout. He's pretty good with the YJ electrical and your symptoms sound like what he just got rid of.
