Does the throttle need cleaning?

[AlinaLee]

The throttle needs cleaning. The throttle is a controllable valve that regulates the air entering the engine. Since the air contains dust and sand particles, impurities are left on the throttle surface as air passes through. Combined with the oil vapor from the crankcase, this forms a black, greasy deposit layer. A dirty throttle can cause inflexible movement of the throttle valve, allowing impurities to enter the engine and affecting normal gasoline combustion. The throttle should be cleaned every 20,000 to 40,000 kilometers. If the driving environment is harsh, the cleaning interval should be shorter. However, excessive cleaning can lead to premature throttle failure, as frequent cleaning gradually removes the special coating inside the throttle chamber, making it more prone to grease buildup and creating a vicious cycle, ultimately resulting in the throttle's failure.
