Thread: Misfires after having new spark plugs & cat put in.. *yay* (+ hard starts)

Those coils suck. Get some ac delco coils.

Haha, will do. Too bad they won't match anymore, but what the heck XD Yeah I remember when I called MSD the rep (who seemed like he was having a long day and his battery was like at 10%) said they dont have ANY products for an 04 GP. It just boggles my mind why they bought those from some local parts store (which has since then closed) if they say they're for like 90's GM engines (I don't recall the specifics).
Oh, and when I took him to the dealer sometime in February I think for the diagnostics the guy did say that "whoever did those MSD coils and wires didn't do them properly" which is what made me look into them in the first place, thus I found out they weren't even made for this car.
