2007 expy el. I have had multiple misfire issues. Replaced plugs and coils, was good. Misfiring again and found heater hose leakage onto the coils on passenger side. Replaced heater hoses. Checking plugs and coils, found the ground MISSING off of #2 plug! I used the updated Motorcraft plugs. Obviously the ground probe went into the cylinder. Would it burn up? Go out exhaust? Or just damage the piston head? No idea how long this could have been occuring. Any thoughts, ideas, advice is always appreciated.
