Jumping on the most recent related thread but maybe someone can point me in the more relevant direction.

Having a grounding issue with my coil pack for 3,4. Grounding stud (spring loaded conductor) holding the coil to the valve cover is really chewed up. My only theory is that a previous/ owner mechanic thought this was a removable screw and used a drill on the soft metal.

The coil will not come off now and its definitely creating rough idle conditions. Anyone out there have any clever strategies for the removable of the coil pack without the complete replacement of the valve cover???

Many thanks in advance MERCI MERCI
