It eventually turned into a solid miss. One of the plugs had failed. The plug looked fine, but I changed just one plug and the engine runs great now. I’d never seen that before. Maybe it’s time to switch to NGK or something.

Thanks for the compliment on my car
That’s exactly what happened to me. Cant buy much of anything thats good anymore I do have autolites in it now and so far its running great
