Is it necessary to clean the dirty throttle?

Regarding the landlord's concern about "Is it necessary to clean the dirty throttle?" The following is my personal opinion:

If the throttle valve is dirty, it should be cleaned;

1. It is generally recommended that car owners clean the throttle every 20,000-40,000 kilometers, but this is only for your reference. The specific cleaning cycle depends on the air environment of the personal car, the type of oil used, the interval between replacing air filters and driving habits;

2. There are no phenomena such as unstable idle speed, engine jitter, obvious increase in fuel consumption and weak acceleration. It is best to clean it;

3. Most of you drive on dusty roads, and the throttle will definitely be dirty, and you may have to clean it once within 20,000 kilometers.
