Asked by Oct 10, 2014 at 09:57 PM about the 2001 Dodge Ram 1500 4 Dr SLT Quad Cab SB

Question type: Maintenance & Repair

I have a, like i said, a 2001 Dodge Ram 1500 5.9L. I had an IAC issue (idleing to high). So i cleaned the Throttle body and replaced the IAC valve got a bad one and replaced it again. A day or so ago it ran great then acted up again. it idles at about 1800 - 1900 rpms and if you hit the gas it will stay at high rpms and NOT drop. so for instance start at 1800 rpms and hit the gas it will jump and stay at 2500 rpms. i have rest the pcm the consumer ways. and try to get it to learn. but to no avail.

am i to impatient should i just drive it around on the highway normally for a while and let it learn over time or is the a ECU/PCM issue.

note: had plenum leak but that was fixed. there are no other vacuum leaks or other problems with the vehicle just a high start idle and higher idle stick if you will.

The thing that gets me is that the idle will stay higher after letting go of the throttle.

also the Throttle position sensor was replaced and there are no trouble codes.

we hoked up a vacuum gauge and it seems to be fine. The mechanic that is helping me is convinced that it is not a vacuum leak we check all the vacuum hoses and needed to replace the plenum gaskets because there was a leak. It will run fine and at times drive and return to idle fine however it seem to be rare and fare in between. If there were still a vacuum leak where would it be? any suggestions?
