Thank you all for your replies.

The battery is new, about 2 months old. I will check the wiring.

Bill, when you say "pre-ignition", can you elaborate? I'm running 87
octane. The motor has 84K miles, and it seems to be running a tiny bit
rough (when idling) and seems to smoke a bit from the exhaust.

I put a new distributor core in her a few months ago. The core had no
adjustment to it, other than a tiny bit of slop in the hold down bolt
and in the plastic cap. I guess I could loosen up the core and cap and
bias the slop in one direction or the other, picking up about one
degree or so. If you think this may help, which direction (CW or CCW)
would I turn the core/cap?

Thank you!

That is computer controlled, you cannot adjust anything. That bit of
slop makes no matter.

Bill is thinking the old engines I think.

I said "pre detonation", spark timing has nothing to do with it:

gasoline, sold without the additives that keep carbon, for one from
forming, 87 octane is OK if you live in Denver.
