Has high miles, this happens on start up sometimes, and sometimes it will stall if u don`t feather the throttle. No codes. once you drive for a while it seems ok. at one time it had a high idle and cleaning the throttle body helped. runs fine at high speed.

Clean the throttle body and replace the IAC motor. Make sure you don't have any vacuum leaks.

Try taking both battery cables off and hooking them together for a minute, then start in up and let it idle in neutral then in gear for a few minutes each, then again with the a/c on.

Clean the PCV passages and throttle body, especially on the back side of the throttle plates and the idle air passage.

Won't it be hard to start with the cables hooked together? Wink

This was the conclusion I jumped to. I hate when I do that, but sometimes personal experiences get the better of me. My 99 Durango had the same symptoms, and didn't set a code. On a bit of a whim, I just replaced the IAC motor. Problem solved. Your results may vary... a lot. Take care. Tom Worthington


If it seems that bracket racing has gotten too expensive for you, maybe you are just doing it wrong.

When you pull the IAC out, look in the port and see how much garbage is on the seat. Looking at the pintle before cleaning will give you an indicator /runout leak. Just some pointers. IAC's are also known to get lazy after a while.

Is IAC the idle control valve?
