> Driving the car yesterday it got much worse. It’s breaking up all over the place. Backfiring a bit too… The backfiring leads me to think it’s ignition. I am going to throw some bkre7s in there @ .028" gap and see how that goes. Then start checking coilpacks and ignitor from there.

Those are the same spark plugs and gap that I use. They work fine for me. No problems so far. Good luck.
