How many kilometers does the throttle change?

The accelerator has no fixed replacement mileage or service life. As long as the throttle is broken, it should be replaced. Throttle is called the throat of the engine, which can control the amount of air entering the engine. After long-term use, carbon deposit will appear on the back of throttle. Car owners can regularly clean up the carbon deposits on the back of the throttle. When cleaning the throttle, remove the throttle, then clean it with professional cleaning agent and wipe it clean. After cleaning, reinstall the throttle and the computer, otherwise the fuel consumption of the car will increase in a short time.
