Removed each spark plug wire from the coil packs today to check the strength of spark. The middle pack is the only one that wont jump from the terminal to the wire. The spark is really really really weak. The others will ark to the pack itself. Coil or ignition module?

O yea. what size is the bolt head that holds the coil pack on.

that is the coil pack. if its the module they will all have weak or no spark evenly almost 99% of the time, or the module will cause it to shut off when hot and start back up after sitting 20 mins. weak spark from one coil is definitely the coil.
