Nathan, Everything they are saying is correct about spark and wires. I have 8mm silicone low ohms life warranty or 8.5 mm MSD wire which is 50 ohms per foot. Either one would be better over stock.

This is essentially a misfire and will cause the engine to run rough. The wire is bad, it should be replaced. You might as well go ahead and replace them all - you have to buy a set anyway. -- Mike [moderator snip] To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
