13 lavida clears the throttle. What if the fuel consumption is high?

It is generally recommended to clean the throttle every 65,438+0.8-23,000 km. Of course, different vehicles, different regions and different road conditions will be different. In actual use, if you encounter problems such as difficulty in starting a cold car, secondary ignition, driving jitter, idling or low-speed flameout, and increased fuel consumption, if you can't find other reasons, you may wish to clean it.

Throttle is easy to deposit carbon, the main reason is that when engine oil or gasoline vapor enters the intake system through the crankshaft ventilation box, part of it will adhere to the throttle and a small part will be impurities in the air.
