2002 ford explorer 4.0l 140K P0302 and P0316. engine shaking. Light came on few days ago and wife drove home 5 miles with it misfiring. Before that no rattles and smooth. Oil level appears to be higher than normal, maybe fuel is in it. (still caramel color)
Removed all APP103 double platinum spark plugs and number 2 had one of the 2 platinum disc burnt off on the spark plug side electrode, while all other were in tip top shape.
Replaced all of them with copper cores 103 and get the same shake and error codes. Order coil pack and wireset today. How does 1 plug melt one all the others look good? Were did the Platinum tip go?
Any advise welcomed.
