TodayI finally got my spark plugs and decided to change them. Overall it was pretty easy until I got to the last spark plug (the one that is in the tight spot). After getting that last spark plug out, I noticed that the old spark plug was denched in MOTOR OIL. (why was it denched in motor oil?) So I whiped off the oil and went along with the changing. Once i got done and put everything back into place. I started the engine and heard a loud misfiring sound coming from that spot with the spark plugs that had motor oil in it. After hearing this, i immediately turn engine off and rechecked the spark plug. To my amazement, the plug in melted off. and the rest of the plug got stuck in the spark plug hole! What should i do???? Help!
