    Not running hot. Changed the plugs, wires, fuel injectors and cleaned the sensor.

    With the work done already, I agree the most likely cause is the catalytic converter needing replacement. Exhaust is not flowing out properly causing the loss of power and the engine to choke itself under higher performance conditions.
