Hi again, NACFC 😄 Although I'm no expert on the Mk2 (NB) your problem does sound like a faulty coil pack, especially with those symptoms of weak spark, then very strong spark, coupled with the intermittent running.
The most effective way to diagnose the problem is to plug into a OBD II code reader and go from there. That should pin-point the problem and save further frustration and unnecessary expense.
Good luck and please keep us informed of any progress...oh, and Merry Christmas to you and yours! 😊
