The IAC (idle air controller) is what lets all of the engine's air in when the engine is idling. The TPS (throttle position sensor) reports the throttle's position to the computer.Thought that was the same as the tps.
And could that cause my problem?The IAC (idle air controller) is what lets all of the engine's air in when the engine is idling. The TPS (throttle position sensor) reports the throttle's position to the computer.

Definitely could cause the problem. Cheap fix or at least cheap to try it.And could that cause my problem?
The IAC provides the engine with a secondary source of air for those times you're not stepping on the gas pedal which opens the main valve plate to let air in through the throttle body. The IAC passes air through itself into the engine whenever the engine is idling and the valve plate is closed, it closes when you step on the gas to open the main valve plate.And could that cause my problem?
Well mine was a automatic. I had the tranny rebuilt but it was taken out of the jeep and put back in buy my mechanic. Then sent out to be rebuilt. It was a total rebuild because it had failed. The mechanic did not clean out the cooling tank and all the shit that was in there went back into the tranny and clogged the pressure switch to the converter.Any luck on this I have the same issue on my 98 4.0
