Is it necessary to clean up the carbon deposit and throttle?

Definitely: 1. The main function of the throttle valve is to control the air intake according to the engine load and when it needs cleaning, which is determined by the driving environment of the vehicle and the control mode of the EFI engine.

2. If the vehicle works in a polluted environment (mainly inhalable particulate matter), impurities on the throttle will soon accumulate, which will affect the intake of the engine for a long time and then need to be cleaned. This phenomenon is most obvious when starting the vehicle;

3. For example, some Japanese engine control systems traditionally like to calculate fuel injection and ignition time by measuring air flow. Therefore, the measurement accuracy of airflow is very strict. A slight blockage will make the engine work abnormally. But for some American engines, there is no air flow as the basis of calculation, and there is not much response.
