Car Forum / Ford / Ford Trucks / September 2007Curious Explorer Question
Hello, I have a 2002 Ford Explorer. Every now and then my idle will go upwards of a 1000 rpm's. It only happens when I run the air conditioner. It happens every once in a while. After a short while the idle comes back down. I was wondering if anyone had a guess as to what was wrong or going wrong. I am thinking it is something like a throttle positioning sensor? Any ideas would be appreciated. Thank you! -- 1000 rpm's in drive not park. Park goes up over 1000 rpm's.  Signature> Hello, > [quoted text clipped - 6 lines] > > Thank you!

Its normal for the RPM to increase some when the AC clutch has engaged thus turning the compressor from the engine through a belt. The AC system regulates the cooling by controlling the time the compressor is run. Engine RPM is a little faster by design during the run times. Listen for the clutch to engage. There is a clack sound then it does. See if the increased RPM is concurrent with those clacks. Thanks for everyones help and advice.
