2001 Grand Cherokee RPM Jumps While In Cruise

The RPM gauge in my 01 Grand Cherokee with the 4.7L will jump 200-300 RPM while driving down the road with cruise on. It will do this regardless of going up a hill or driving on a road with no elevation change. Most recently, it starts to stutter when going up small hills and comes out of it when the overdrive kicks in. Any help or ideas would be greatly appreciated.

Hi,

it sounds like the TPS (throttle position sensor) is acting up. To test it grab onto it and push it around, if the rpm's change while you are doing that it is the problem. It is located on the side of the throttle body.

Thank You

When I engage the cruise control is holds speed but rmp surges periodically around 2-300 rpm.


It could be your transmission trying to find the right gear it will jump around on diffrent road surfaces and going up hills/down hills. It is usaully noticable on cruise because it is at a constant speed and your thinking why would it need to shift. Sometimes it doesnt even really shift the gear its so inbetween it just jumps back really fast.

Will start but rpm gauge jumps up and down then it dies


The problem you describe has NUMEROUS causes. Most common of these is a COIL is going bad. The RPM gauge gets its signal from the ignition coil/crank sensor circuit (could be either one OR could be the wiring between the engine control module (ECM) and the engine components. Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there.

Rpms jumping


Hi, I had the same problem, the car kept accelrating and the RPM needle kept jumping, I turned off the cruise control and I had no problem after that. I do however have problems with my cruise control as I do other electrical issues. Anyhow, I believe this would fix your problem. Please let me know what happens:)
