I had posted about my 85 skipping and missing and all the stuff that I changed, wires,o2 and even injectors, What it was was a large piece of the cat "guts" broke off inside and would sometime block the exhaust exit. It would run rough and lack power or if the piece cleared the exhaust it would run good. It was driving me nuts until I put the injectors in and didn't move the car. It ran terrible. I jacked it up and dropped the exhaust and there was the piece blocking the exit. Pulled it out and fired it up, ran great. I now have a very large piece of tail pipe there. It is really breathing now. thanks for trying to help with this. You guys gave me some good things to try, This was one of those things that drive you nuts. :D
