just pulled the top part off my MSD Blaster 2 coil (where the plug wire plugs on) and where there is sopposed to be a metal piece to make contact with where it plugs in the coil...its cracked in a few places and there is a screw in there with wire all around it...talk about a hackjob....now my question is, would this cause a small surge in the idle? when i pulled the plugs to do a compression test, there was a little bit of unburned fuel on the plug....could this coil hackjob cause the fuel not to burn fully?
