Default When green wire goes bad, how does it run?

My83 suddenly runs like total ****. Just started one afternoon, and Ive parked it since.

All 8 cylinders fire, and they all fire the same "really ****ty"...at WOT doesnt get out of its own way.

INtake refresh last May, all new injectors as well.

Sounds like a bad green wire. They either run like dog sh*t or don't run at all. If it isn't bright green, replace it.

Wouldn't hurt to replace the cap and rotor at the same time.

You know the drill. You checked for spark. If it's a strong spark and timing is OK, look elsewhere. Next step, at least in my protocol, is a casual fuel pressure and delivery test.

I had a random misfire above 4k in my 79 that was from a failing green wire.

ya...theres no misfire. I havent checked for oil/corrosion at the coil, and cap/rotor are new last spring.

Runs like an old truck that huffs and puffs, but wont really go anywhere. Will catch video for sound this eve.
