Nonetheless, when >> I run the truck in pitch dark and I look at the #6 wire, I see arching right >> behind the boot. Probably the outside of the spark plug is "tracked.' Look for a thin line on the shell. you may be able to feel it with a fingernail. When a track burns down the outside of the plug it damages the plug and the wire boot both. Replace one and not the other and the arcing will continue and your new plug or wire will be damaged. Don www.donsautomotive.com >> 1.
