This is a strange problem. no one iv spoken with has ever heard of something like this. i was driving (87 gn) and all of a sudden its running like hell, popping slow etc. i got it home and popped the hood. i notices a spark plug wire unattached. ( strange, but ok) so i go to reattach it and noticed its hollow. the metal inside the plug is gone, and the ceramic is blown apart. i diddnt have a gapper and dint have the correct gap #s, so i replaced the spark plug with a new one leaving it gapped as it came. a few days ago i notice the fuel injector on the same cylinder was leaking fuel. im not sure which happened first, or even if one can cause the other. what the hell!! anyone have any suggestions?
