Engine miss

I think I have found the problem.
I've been using some neat old spark plug connectors. After changing the plug wires with no change to the miss condition, I noticed one of the plug connector felt a bit funny. Upon closer inspection (meaning putting my glasses on), I found that one connector had a loose internal screw (they screw onto the plug wires), and it was somehow broken.
I replaced it and it seems to have cured the problem.
I'll know for sure tomorrow when I have the opportunity to actually drive the car.
Funny how the smallest of items can create havoc on my old brain.
I'll report back tomorrow one way or another.
Thanks again, everyone
Jim
