1993 Jeep Wrangler Problems

Exhaust & Emissions -- Verified

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.

Exhaust & Emissions -- Verified

A ticking type noise may be noted from the engine area due to an exhaust manifold that has cracked where the pipes are welded; cracked manifolds should be replaced.

Engine -- Verified

Engine oil leaks from the valve cover gasket, oil pan gasket and timing cover gasket are common.

Engine -- Verified

Some models are susceptible to rear main oil seal failures in dirty or dusty conditions. As dirt and dust collect on the oil seal, the abrasion wears through the sealing surface. A spacer is used between the bell housing and engine that has a small slot in the 12 o'clock position. Filling this slot with RTV silicone and cleaning the seal area can help prevent damage to the seal.

Brakes -- Verified

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).
