Well I haven't done much but R&R so far. With mine it's real funky because it is intermittent and sometimes it would stop doing it, but now it just progressively gets worse until I pretty much can't drive it. I can tell it is running really really lean when it gets to that point since my car usually runs stupid rich normally.

However, when it does get to that point, I just pull the coil pack and throw on another and I'm good to go for a little while. I literally alternate between two coil packs every three or so days. Funny thing is when I pull the coil off, it tests good. I haven't tested it right after pulling it off but they tests good everytime.

As soon as I put the other coil on it runs fine for a couple days, starts hickuping, and progressively gets worse until it sounds like it's running on two cylinders and has very little if any acceleration.
