Is it necessary to clean the throttle frequently?

Sometimes we go to maintain our car, and 4S shops or maintenance personnel sometimes ask us if we need to clean the throttle. So is it necessary to clean the throttle frequently?

Do not clean the throttle frequently, because the surface of the throttle has a dust-proof and antistatic coating. If the throttle valve is cleaned too frequently or the cleaning solution is not used properly, the coating will be lost, which will make the throttle valve dirtier.

After long-term use, the throttle valve will accumulate a lot of carbon near the airflow valve plate, and even block the reserved idle air intake. These problems will lead to slow throttle response, unstable idle speed and even flameout. Therefore, it is recommended to clean the throttle every 20,000 km to 40,000 km. If the vehicle environment is bad, it is necessary to shorten the cleaning interval.
