How to Replace TPS (Throttle Position Sensor) Jeep Cherokee XJ 4.0
A very easy fix which should take no longer than 10 minutes at most, well, as long as you dont have any stripped out bold/ screws. I diagnosed the ploblem when the cherokee would just idle up and down all by itself and won't/ couldn't keep a constant idle speed. $36 from the parts store and the problem was fixed!
