Engine Performance problem
2003 Dodge Caravan 6 cyl Front Wheel Drive Automatic 90400 miles
I have a KOER P0302 misfire code. Did not happen until I had plugs and wires replaced (bad move). New coil pack also replaced. Injectors cleaned when plugs and wires replaced. Mechanic can find nothing to cause misfire. Takes about 1 week for Check Engine light to come on after being reset.
