Spark plug will not tighten!!!
Hello Board, I have been meaning to ask the question, but I have never gotten around to it. Now is the time!
My #4 spark plug will not tighten at all, it seems that the previous owner somehow ruined the threading in that hole. With the plug wire on it, I can physically feel the spark popping and jumping. Is there any damage or performance loss that can be linked to this loose spark plug??
