Vehicle has hard starts and frequent hesitation and stalling, at all speeds city street driving as well as highway driving. I have had a new distributor cap, rotor, plugs, wires, coil, installed, yet symptoms persist. Sudden deceleration at highway speeds is a seriously dangerous condition. My research suggests this is a common problem with the Jeep Cherokee xj. I narrowly escaped a crash on a busy interstate highway this morning at freeway speeds. Jeep ought to be aware of this problem, yet there seems to be no remedy for owners. I would at least like to know what the problem is. Possible remedies (from my research) include multiple parts and many hours of labor: O2 sensor, throttle position sensor, crankshaft position sensor, plugs, wires, cap, rotor, fuel pressure regulator, engine control module, alternator, neutral safety switch, ballast resistor, transmission control module, torque convertor, power control module, transmission control solenoid, etc. What is causing all of these vehicles to stall dangerously?
