Did a Quick search for this but couldn't find what I was looking for.

My coil pack has gone bad three times now, in less then 5 months. This last time it lasted a little over a week. luckily it is still under warranty so I can get it replaced for free.

My problem is this; what the hell is causing it? Has any one had this problem before? Any help is appreciated.

By the way I have an 03 cavalier with a dual cat-back exhaust, cold air intake, and the b and m shift kit for an automatic.

Poor electrical connection some place. Coil packs are very simple devices.

Yeah thats what I'm thinking, but I'm not sure where. It started acting up after the Shift kit was installed but it didnt happen until 6 months or so after I installed it. Is it possible that this is messing with the coil pack, or something?
