I’m trying to chase down this misfire. It could be an issue with it running too rich or lean but I don’t think so. I’ve replaced one of the coil packs, plugs, wires, rotor, cap, and points (gapped to 0.45mm or 0.018 inches). I haven’t replaced the condenser because I’m not sure which one it is. Are there two that are noted to the outside of the distributor? It seems to do good at higher rpms.

So its a 79 I assume? Not enough details here to help really.The video is so short its hard to tell and then it jumps to cat video LOL.

 

Unless you know it is damaged, hang on to the replaced coil - assuming it is one of the originals. No replacement is as good as those original coils. Pay very careful attention to your grounds and in this case also to your insulation. A cracked section of wire can have the effect you describe.
I don't believe there is anything the Factory Service Manual about this problem, but if you haven't done so already you can't go wrong downloading a free copy . The link is in my signature.

 

It’s a 79 yeah. I’ll upload a longer video in a couple hours. Sorry lol

 

The original coil was dead. I unplugged it while it was running and it didn’t change a thing. I’ll check the wiring. Thanks for the help
