Start a new Jeep Grand Cherokee question.

Asked by Apr 27, 2013 at 10:22 AM about the 2004 Jeep Grand Cherokee Special Edition 4WD

Question type: Shopping & Pricing

I am driving my Jeep along the road at about 120 km/h and the rpm will start jumping around from about 2000rpm to about 2500rpm.It will do it for a while then settle down and then do it again.I replaced the idle control unit about 6 months ago and this helped .Do you think i need to replace it again or not.It will only shoot up and down to 2500rpm ,it does not stay up there but it is a weird feeling when you are driving at a constant speed but the vehicle feels like it is changing gear or speed .Any ideas appreciated.

Have the computer system checked, it may be the transmission, my 02 started doing something similar and had to replace the tranny.

check the throttle position sensor. i assume the wj's had those

Yes, I would start with the much cheaper throttle position sensor first. Or, at the very least, try cleaning the carbon out of the throttle body and see if that helps at all.
