Quit crapping up threads. I'm getting tired of it. This is a warning for both of you.

Sorry OP, your looking for the ICM. Try finding one in a local junkyard off of any SeriesII or SeriesIII 3800's. Remove the coil packs and the 7mm bolt holding it in. Reverse order. If all else fails to rule it out, take your current one to an auto parts store and have them test it for free.
