2000 Cherokee Sport 150,000 miles: Jeep runs fine for about twenty minutes give or take, then starts misfiring, sputtering, stalling, sometimes I turn ignition off and immediately back on and I am fine for a few minutes. Codes are loss of ignition primary signal, loss of camshaft crank signal and of course various accompanying misfire codes. I have replaced crank and cam sensors, oil pump drive housing, removed the entire engine harness, inspecting cleaning, re-taping, and reassembling every connector with dielectric grease. I recently (within the year) have replaced all six injectors, coil, plugs. I have "seafoamed" through the throttle body. My next stop is computer or the flexplate. Internet research has been inconclusive other than ZJ's seem to have a similar problem but opinions differ as to the primary cause. PLEASE HELP!!! It drives fine usually just long enough for me to get to and from work, but it is driving me crazy. I had a mechanic at the auto hobby shop (Im in the military) look at it with me and he's stumped- but says there is only a 1% chance that it is the PCM. The sensor voltages and wiring test fine, they are cheap aftermarket sensors- I have ordered mopar ones just to eliminate the possibility before I drop the tranny or replace the PCM.
Anyone ever actually resolve this issue?
