How long does it take to clean the nozzle and throttle?

Generally, the nozzle should be cleaned once every 2 years or 6W km; The throttle is generally cleaned every 20,000 kilometers or so. The following is an introduction about the influence of the nozzle and accelerator not being cleaned: 1, slightly dirty: no influence on the vehicle, no fault phenomenon. The vehicle can be used normally without cleaning. 2. Generally dirty: It may cause abnormal engine noise, which will lead to increased fuel consumption, decreased power and poor comfort. 3, very dirty: it will cause the vehicle not to idle. When the throttle is released, it will turn off and it will not run normally. At this time, be sure to clean it. As for how dirty it is, you can use a computer to detect the opening of the throttle at idle speed. If you don't need a computer, you can open the throttle intake hose and visually check the degree of dirt. A slightly experienced maintenance technician can also judge the degree of dirt.
