So I still have a problem some times over 5k the car breaks up really bad. I have an MSD coil, ICM cooling mod and running on 93 octane. Still on stock plugs and wires with almost 55k on them. I did a little investigating and heres what I found. Anyone know if this would be the cause of my problem? Thats the coil wire if anyone is wondering.

 

Ummmmmm, yeah. I would replace the coil and the coil wire and see what happens. I bet that fixes it right up. Make sure you use plenty of dielectric grease on the wire ends to help prevent this in the future.

 

does anyone know if a GM dealership would stock a coil wire?

 

I'd suggest you replace all the spark plugs wires. The GM wire set, that includes the coil wire works fine. You can also get a set of aftermarket wires like the Accel 9000's.

 

Well the thing is, I have some Hooker LT's that I am going to be installing in a couple of weeks and was planning on doing an OVTC wire set from elitesparkplugs, but it seems they are having there fair share of issues...
