I just noticed tonight without any lights on in the dark that my spark wires spark when touching any metal in the car. The car has a metal four spark wire holder on the side of the cylinder head and I noticed I could see light or sparks go through the metal holder. So I took them out and I could see sparks or light on any metalthe wires touched. Whats up with this? I havent ever noticed this on any other car or truck of mine. Is this a ground problem or what?
