Running rich as all hell at idle, BTW

I've been doing it for 10 years with same spark plugs, personally. But you can smell pure gas from the exhaust.

We need to get that sorted too.

Yea exact same thing for me. Is it okay to leave this misfire like this at idle once the car gets moving it's fine.

I don't know. A 'misfire' in my dictionary would be a big deal. Not sure what you mean, that's the problem. I tiny little putt once in a while isn't a big deal, but certainly related to combustion.

I redid my grounds as I was suggesting, (it doesn't fix a rich condition, obviously) and it was a pretty remarkable difference, especially at low RPM. Car is ALIVE now. Can't wait to put in new fluids and plugs and everything else.

I was thinking you could try making sure you have excellent grounds - that and/or gaping your plugs a little closer to make up for the increased resistance of older connections. A rich condition isn't as explosive also.

And BTW, I can't find the info on grounding ATM. There's a thread somewhere I didn't find.

Yea it just a little put here and there but I dont get why it's doing this and why no cel ever.
