So it was Magic!?

Drive to work this morning was hiccup/problem free again. Talked to a mechanic buddy who lived GM for over 10 years. Asked if he's ever seen a spike in rpm from one bad coil, without registering misfire, and not retarding the rpm for a second like a misfire would. He said he had, it's not common.

If that's what happened here...I gotta say. That's a new one for me as well and a definate lesson on something that makes little sense. Going to keep on driving to see if it will ever do it again. Meanwhile..the shifts are stout and the car as always pulls nicely. Might be time to tune the little white Regal.
