I have a 96 Jeep grand Cherokee... 4.0L 4x2 w/ the same problem w/ 202,000 miles. and it's been recently that i've been working through this problem for Ignition Coil #1. So far i've changed the Throttle Position Sensor, fuel pump, fuel filter, both Oxygen sensors, the engine wire harness, the PCM, and ignition coil, camshaft position sensor, crankshaft sensor, the rotor, distributor cap, ignition wires and spark plugs. I have totally run out of ideas. I have some of the diagnostic manuals for the GC and tried following the wiring schematics. There is a [B]grey/white[/B] wire that goes from the coil to the PCM, a [B]dark green/orange[/B] wire that goes from the PCM to the ASD relay, according to the schematics, these wires are linked to the Primary Coil#1 code. i could see how that could work out w/ just placing a wire directly from the Coil to the PCM, but i've replaced the engine wire harness so i cant imagine how i could have the same problem, pls help!!!
