1990 Jeep Wrangler Problems
The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.
Due to warped front brake rotors or variations in the thickness of the rotors, brake pulsations may develop. The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).
