I have a 1966 Ford Galaxie 500 sedan with the 390 2bbl, automatic trans, power steering, power brakes. All stock. The problem i was having is when I apply the brakes, the engine would start to run real rough from about 10 mph until a few seconds after a complete stop. Once stopped at the light, engine will be running really rough for a few seconds until engine smooths out. It would do this about everytime I stopped and started out of nowhere. Then the next time I started it, it would barely run, wouldn't accelerate, just sounds like it was sucking air but no rpm raise. Now the problem im having is it won't even run. After that last drive, I was stranded because it wouldn't start. Kinda started once after that with my foot to the floor and it ran extremely rough at low rpms with full throttle but if I let off the gas it would die. Confuses me because I drove It to school that morning and It was fine, now all of the sudden It won't run. It has new points, condenser, rotor, cap, wires, plugs, plug wires, fuel pump, and carburator was rebuilt. Thank you !
