IT seems to happen like clockwork. The engine will run great for about 15-20 minutes and all at once as though you flipped a switch the engine will begin to misfire so badly you cannot even rev it up.

Well today it did it in the shop and somehow the engine stayed running at idle BARELY (400 rpm) and that's when I noticed and verified with an infrared thermometer that the header primaries on the passangers side had gone cold compared to the drivers side.

Sounds like a bad coil-coils but being unfamiliar with these ignition systems does this sound feasible? And NO I can't hook the box up to my laptop at this time as it lacks a commodore64 era connector.

Losing 12V power to that bank would do it. Bad connector, loose wire, bad ground, the usual suspects.

I'm thinking its a ground issue.

UPDATE

I solved the issue and it was due to the strangest thing.

A blade of grass had found its way into the drivers side coil connector and was laying across several of the pins. I blew the connectors out and it hasn't misfired in a couple weeks now

That's so be strange stuff, what are the chances?

IKR.

It had to start doing it when I was tapping on various things with a screwdriver or I would have NEVER found it.

I wonder if this may have been playing a big part in my intermittent no crank issue I was having too

Glad you found it.

Now where are the burn out video? Or are you waiting to find a commodore 64 on ebay

This is why it is so hard troubleshooting problems over the internet. Too often it is something stupid that you just kinda have to see to find.

No burnout. Simply due to the lack of a camera man.

Will a sound walk around suffice
