Is it necessary to clean the throttle valve recommended by the garage?

Many car owners always suggest cleaning the throttle when doing maintenance or maintenance for their cars. Many car owners don't know when to clean the throttle, so they spend a lot of money in confusion. The throttle actually needs cleaning. However, it needs to be handled more selectively according to the state and service time of the vehicle. If the throttle valve is not cleaned for a long time, carbon deposit will form on the inner wall. It leads to unstable idle speed of the car and increases fuel consumption. Therefore, if these situations occur, it is necessary to clean the throttle.

When the throttle valve needs to be cleaned, the engine idling is unstable at first. If there is too much carbon deposit in the throttle, it will lead to a smaller opening at idle speed and make the engine unstable at idle speed. If it is found that the engine is unstable at idle speed, it is necessary to clean the throttle. Secondly, the throttle response time increases. After the accelerator is not cleaned for a long time, it is difficult for us to accelerate. The reaction time of the throttle will be longer than usual. If the reaction time of the vehicle stepping on the accelerator increases, it is necessary to clean the accelerator. Finally, it is decided according to the purpose of the vehicle. Generally speaking, it is more appropriate for vehicles to clean the throttle for 20,000 kilometers, but if there are frequent traffic jams, the frequency of off-road vehicles is higher.

First, the engine idling is unstable. Is the throttle valve taking in air and entering the engine cylinder? Throat? If the throttle has serious carbon deposition, the air will be blocked when entering, so the idle speed is unstable. Therefore, when the engine idling is unstable, it is necessary to clean the throttle in time.

Second, the throttle response time is increased. If the throttle valve is not cleaned for a long time, the air entering the cylinder will be affected after more carbon deposits are formed. When we step on the accelerator, the reaction time of the vehicle will increase. If you feel that the throttle response is not timely, you'd better clean the throttle.

Third, it depends on the purpose of the vehicle. If the vehicle often travels at high speed, and there is no idling or slow throttle response, then there is no need to clean the throttle. If the mileage of the vehicle reaches 20,000 kilometers, or the vehicle often goes off-road, it still needs to be cleaned.
