Is it necessary to deeply clean the throttle?

It's not necessary. Cleaning the throttle can effectively prolong the life of the engine. Carbon removal can improve the accuracy of air intake and fuel injection, improve fuel efficiency and reduce fuel consumption. If there is too much sludge in the throttle, the engine will not be able to accelerate and the fuel consumption may deteriorate. Therefore, the throttle valve is a valve to control air to enter the engine. It mixes gas with gasoline to form a combustible mixture, which forms a driving force after combustion, connecting the air filter and the engine block, and is the throat of the automobile engine. For the throttle, a steady stream of stains will lead to the wrong throttle opening, and impurities in the air will enter the engine combustion chamber. So as long as ordinary cleaning is carried out, there is no need for deep cleaning. The advantages are that it can remove carbon deposit, improve air intake and fuel injection accuracy, improve fuel consumption and prolong engine life. If the throttle valve is not cleaned regularly, the engine will be abnormal, mainly manifested as unstable idle speed, sudden opening of the throttle valve during operation, power drop and so on.
