    Sounds to me like you need a new fuel pump. Fuel will still go through the line so that the car can idle but will not flow fast enough to rev up because the pump is not pumping.

    Actaully, a code 43 is for the heated o2 sensor OR the fuel supply system, but from your symptoms I would say its the fuel.
    check your fuel filter also. . .
    if you do all of this and the engine stillwon't rev, then swap your map and tps sensor wires
