Re: Need tuning help for simple system.......
I told him about the wires they sell at Advanced Auto Parts...Autolite Professional I think? They are lifetime and about $25
Been running these for years in local trucks. They are much more repeatable that the big $ aftermarket ones.
Got some cheapie Auto Xtra ones from Rock Auto on my truck now, with heat sleeves over the boots. So far, so good.
Most common reason for wire failure in these trucks is improper wire routing, which leads to burn-through or other heat-related failure. If the stock heat shields and wire looms (or a reasonable replacement) aren't in place, you're likely to have problems.
