Cracked coil packs show symptoms particularly during cold and wet weather when moisture has entered the engine compartment. Cracked coil packs can cause a rough-running engine or a misfire at idle. Moisture that sits in the crevice of a crack on the coil pack will allow a spark (arc) to travel the length of the crack until it reaches a ground source, where it will cause a direct short. Electrical sparks jumping from a crack in the coil pack case accompanied by a loud electrical clicking or snapping sound indicate a cracked coil pack.
