Why waste oil after cleaning the throttle?

Cause of fuel consumption after cleaning the throttle: 1. After cleaning the throttle valve, it does not match with the engine control unit or the matching is unsuccessful; 2. Because the self-learning ability of the engine control unit of some models is poor, even if the throttle and the control unit have been correctly matched, the fuel consumption will increase in a short time, but it will return to normal after driving for a period of time. Throttle is an important part of EFI engine system. Its upper part is the air cleaner grille and the lower part is the engine body, which is called the throat of the engine. When the driver steps on the accelerator pedal, the signal is transmitted to the control unit, which controls the opening of the throttle valve, thus ensuring that the engine can have sufficient air intake. When the vehicle is shaking and the acceleration is not smooth, it has a lot to do with the dirty throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and energetic.
