Re: 2000 TJ Stalls when driving
Welcome to the garage.
Did you already measure the wiring from the PCM to the ignition coil? You need to measure for continuity, while messing with the cable loom, and see if there is no wire break. You also need to measure from each wire to ground, to see if there is a problem with a shaved wire which shorts to ground.
A known problem with the 4.0 is wire shaving at the back of the cylinder head. The cable loom passes close to a stud and can shave due to the movement of the engine while applying torque (acceleration).
