hi all, My dad owns an XM 2.0l on a K plate. (unlucky him lol) The coil pack has a poor spark or no spark at all on cyl #1 causing a misfire at most times. The other three ht leads /plugs have a good spark, does this means the coil pack is ok? Could this be more of a ECU problem or is the coil pack borked? ps. Dont blame you for not helping getting another c**p XM on the road..lol Thanks in advance for any advice. regards jj
