It's the stock '92 Mustang coil. I'm using one of those pocket circuit testers with the little probes and the sweep needle. My checks have been both with volts & ohms....

I'm certainly capable of a backwards install, Mike but this time the coil plug only goes on one way.

Actually sounds like a weak coil, I'm certainly not claiming any expertise on electronically controlled engines, still a neophyte on them but I have learned that good grounds are essential.
Yes, Dave, I've checked all those grounds and they seem to be good. Perhaps I should spring for a new coil and see if problem is solved.....not sure what else to do at this point.....

Thanks for the input, guys!!!! Always MUCH APPRECIATED!!!!
