I have a 2003 Jeep Grand Cherokee Laredo. Inline 4.0 6-Cylinder. I keep getting the following codes:
P0300: Random/Multiple Cylinder Misfire Detected
P0302: Cylinder 2 Misfire Detected
P0303: Cylinder 3 Misfire Detected
P0304: Cylinder 4 Misfire Detected
P0305: Cylinder 5 Misfire Detected
P0306: Cylinder 6 Misfire Detected
Sometimes I only get the PO300 Random misfire.
One time I got P0352: Ignition Coil "B" Primary/Secondary Circuit
The car will run rough and lose power. I reset the codes and it runs fine. I have replaced the Camshaft Position Sensor, The Crankshaft Position Sensor, The Ignition Coils, and the Spark Plugs. On an unrelated issue I rplaced the throttle position Sensor. Really gettin frustrated, where do I go from here?
