I bought it, drove it home, it started the next day. However, it ran rich, alot of smoke. (alot) Sputterd. Black sooty stuff came out the exhaust. Had a horrible exharst oder. Now it will not start. Replaced distributor, rotor, coil, wires, map sensor, and checked and rechecked timing. Could the catalytic converter be pluffed? I have spark and fuel. However, fuel injectors injecting too much fuel and flooding plugs. I have gas in with oit getting past rings as I try to start it again and again. OH, changed the throttle body also. Please help........It will not start.
