so the car has being doing this for a while now, it has been passing raw gasoline through the exhaust and smoke. I have changed the oxygen sensor, the fuel regulator, the spark plugs and wires, brand new distributor cap, fuel filter, and cleaned throttle body (with throttle body cleaner of course). I blame my father for putting the lucas fuel injection cleaner. The only guesses i have is that its the injectors or vacuum leak.

    If you are passing raw fuel, it is most likely the injectors are over supplying fuel and/or are not shutting off correctly. It must get lousy fuel economy, no?

    real bad, the cylinders end up getting so flooded it just shuts off. So does that means its an electrical issue. Also at highway speeds it runs perfect, this only happens when idling. The problem was not as bad a few months ago but sense then i drove it on two 600 mile trips (never overheated) which amplified the symptoms to what it is now.
