high idle

Recommended Posts

The first start is usually always good. But after that like around town it wants sometimes to go to like almost 3000 rpms when I go to start it and I have to shut it down then restart then it goes away. Its a very intermittent thing.


1988 comanche 4.0 5 speed manual

i replaced the egr, injectors, plugs, cap.

TPS and ICU about a year old now both are neighoffs.

I replaced the cps as well. In fact I have replaced everything but the computer and the map sensor.

Clean the throttle body and IAC real well as suggested. If that doesn't help, then you are likely having an issue with the IAC itself. I had the same issue, but after spending the money on a new IAC, TPS, MAP Sensor, Temp Sensor etc, etc... I found my problem to be a ground issue on the right side of the block :fs1:

Well I think my throttle cable might be sticking. When I was driving home the other day on the freeway I took my foot off the gas and the truck kept maintaining speed. Well I don't have cruise control. So I don't know if thats an issue with the pedal or the linkage or what? :hmm:
