Dodge 2001 ram / v8 5.9....i had replaced the idle control valve, this seems to have corrected 3/4 of the problem it does not rev as high, and the problem comes and goes it's not persistant, while checking the throttle body when it was running ok and warm it did want to rev up briefly then corrected its self, the cables for the throttle do have a little play but they are not bound up. I have been using a fuel injection cleaner, and run 93 octane fuel, ......under cold conditions i had taken the throttle pedal and lifted it up and just let go and just by doing that can cauce the rpms to fluctuate.....hope you can get me pointed in the right direction!! John in fairfield PA USA!!
Have you by any chance taken a multimeter & tested your TP (throttle position) sensor ? If you think you might know how, let me know & we'll guide you through it. If not, at least take wiring plug off & clean both plug & TP sensor contacts with contact cleaner, and inspect for any corrosion while doing it. When putting plug back on, use a little di-electric grease in the connection. Have you sprayed your throttle body & throttle plate good with throttle body cleaner recently?
Glad to help, hope all stays well, but at least it sounds like we're in the right area anyway. All the best, Take Care. Motor1258

Motor1258 i do not have a mutimeter but did take off the wiring plug like you had suggested and cleaned it with contact cleaner, and yes it does seem like the problem is gone, but i have only had 2 cold starts, the engine revs up and back down to 6000-7000 rpm and stays constant with no fluctuation with the gas peddle like before, Thank you so much for the imput the problem was driving me crazy! i think if starts acting up again i may have to get a new TP sensor.I did not play around with this before becauce the book told me to take it to a dealer. Yes cleaning the throttle body was the first this i did when i went looking for the problem.When i disconnected the wiring plug there was no signs of any corrosion that i could see.
Thank you so much for your solution to my problem!!!
Thanks again!
