Is it necessary to clean the throttle when driving 50 thousand kilometers?

It is necessary to clean the throttle valve after the car travels 50 thousand kilometers. Because the throttle of the car is too dirty at this time, it will attach a layer of sludge and dirt to itself and the inner wall of the nearby airway, which is called carbon deposition. If the throttle valve is too dirty and not cleaned, it will affect the intake of the engine, leading to engine idling jitter and flameout. Moreover, the acceleration of the car will not be smooth, there will be a sense of frustration, and fuel consumption will also increase. Under normal circumstances, clean the throttle every 20,000-30,000 kilometers. It can be cleaned with special foam cleaning agent or disassembled for cleaning. However, 4S shops or repair shops usually use the "drop bottle" method for cleaning, that is, when the engine is running, the cleaning solution is continuously sprayed into the intake pipe. Although it takes a long time, the operation is relatively simple, and the intake pipe can be cleaned by the way. However, frequent cleaning of the throttle is not recommended. Too frequent cleaning or improper use of cleaning solution will cause the dust-proof and anti-static coating on the throttle surface to fall off, and then the throttle will become dirty more easily.
