Heavy Metal Thunder
Decided to change my plug wires today & after removing the wires from the coil pack terminals, I noticed that 4 out of the 6 terminals were rusty looking & so were the boots on the spark plug wires that came off those 4 terminals. I took a little sand paper & sanded them off. Also tested the coil pack & all the #'s were around 13.5. which I was told is good. Is sand papering them the proper way to clean them up & what can I do to prevent this from happening again?
