a faulty throttle pedal sensor will produce a sluggish or low power response from the engine

I'd 1st suggest disconnecting the pedal sensor and use some switch / contact cleaner on both sides of the connector and check the wiring for any damage

If this looks OK then I'd consider replacing the sensor with new
