Is it necessary to clean the throttle in Ming Rui?

Generally, 4s shops will look at the number of kilometers. I suggest you clean it once every 20,000 kilometers. But not necessarily. Do you feel high idle speed? Average fuel consumption increased? Or is it shaking badly when idling? If not, there is no need to clean it up. And if it is not always high-grade and low-speed, the gasoline engine oil is always good, or additives are often added, the carbon deposit and colloid on the throttle will not be so serious.
