Well, its official, Accell COP's suck! Not only were they the problem, but when I went to take one of them out, the damn boot broke off. The piece left was about flush with the top of the plug and was a pain to get out even with long needle nose pliers. Took it out for a test drive, and sure enough, it ran like a scalded ape (thats a very good thing). Thanks for everyones help.

It's not just the Accells. Most aftermarket COPs for the 3V are absolute crap. I haven't heard of anyone having failure with the MSD COPs, but MSD doesn't make any rating claims about their COPs, so they could be the same as stock for all I know. After my experience with Granatelli's CRAPPY COPs, I will just stick with the stockers.

No they won't, mine failed after 1 1/2 years or so. I just put the stockers back on. My car ran pretty good until I tried to accelerate, then it shook and felt like the clutch was slipping.
