Mercedes-Benz s500 didn't respond when it hit the throttle.

Your condition is usually caused by a damaged accelerator or accelerator pedal position sensor.

I suggest you go to the repair shop to look at the data flow and analyze it. Generally, apart from the sensor or throttle, it is the engine computer and wiring problems. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
