1992 Jeep Comanche Problems
RepairPal has identified the most common problems with the 1992 Jeep Comanche based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Exhaust manifolds commonly crack where the pipes are welded; the manifolds should be replaced.
The throttle body may accumulate an oily, black residue in the bore and on the throttle plate causing hard starting or possibly stalling when coming to a stop. The throttle body should be cleaned during regular maintenance but do not spray cleaners directly on or at the throttle position sensor (TPS) as this can damage the sensor.
The head gasket may seep oil externally. An updated head gasket is available that should correct this concern.
The outer exhaust manifold studs can break and cause exhaust leaks, commonly noted as a ticking type noise. The outer studs, clamps, and nuts will need to be replaced and are now being tightened to a reduced torque value (20 Nm/180 in lbs).
