I've got a 1984 Camaro Berlinetta (305 V8) I'm trying to get running right again, and I've grown rather stumped. I think the blame may lay on the pathetic Rochester 4-bbl "feedback" carburetor, but I am not sure. When you start it cold, it runs very rough until the choke opens, then runs great. You can go out and drive it for about 15-20 minutes, and it'll run beautifully, and then after that when you put your foot into the gas it'll start missing and spit back thru the carburetor, and the longer you drive it the worse it will get. I've sprayed cleaner into the carburetor, removed the catalytic converter, replaced the O2 sensor and the coolant temp sensor for the ECM as well as the air filter. I de-activated the A.I.R. system long ago. I've put an accel HEI Super coil, new plugs, and new wires on it within the past couple years, they'e got less than 15k miles on them. The car sat for about a year, after my ex took it, and I've finally gotten it back and I am trying to make it run right again. I wish everything were as simple to work on as the 6 cylinder '68 Plymouth Valiant that is my daily go-to-work car. anyone please lend me some advice to get this camaro back running right again, its too nice of a car to go to waste.
