2002 Ranger- Cylinder 6 missfire-PLEASE HELP
CEL came on last week. Truck is running very rough, shakes at stop lights, hesitates when taking off.
Pulled a P0306 code off of it yesterday. Changed spark plug, it was white. Cleared the code, now it's back on after driving 5 miles and running rough again. We have changed the Ignition Coils & Spark plus (not the wires yet).
I'm trying to sell it and have no idea where to go next with it.
Any help or suggestions would be greatly appreciated.
