I have a 1993 GMC with a 350, it is the electric carbed motor. I know my quadrojets not these computerized things. Anyways, if the truck sits at idle for a short period of time, it bogs and when you give it any gas it stalls. It stays at idle (100km/h) on the highway no problem, but if you stomp in it, again it bogs. It is pumping a crap load of fuel into the carb, anyone know what it could be?
Note* Brand new O2 sensor.

Your o2 sensor detects how well the fuel is being burnt by reading your exhaust gasses and is what directs the fuel injection to pump more fuel or lean out the fuel flow. When they go bad, the motor will always run rich. I would start by looking there.
