How long does it take to clean the throttle?

The throttle needs to be driven for about 20,000 kilometers for cleaning. Throttle is a controllable valve that controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture and burn successfully. The symptoms of throttle failure are: 1, unstable engine idle speed or no idle speed; 2. The engine is difficult to start; 3. The engine has insufficient power, poor acceleration performance and unstable operation. The cleaning method of the throttle valve is: 1, turn off the ignition switch and remove the negative electrode of the battery; 2. Dismantle the throttle pipe, air inlet hose and the screw for fixing the throttle valve in turn; 3. Clean the throttle with carburetor cleaner; 4. Install the upper throttle in the order of removing the throttle; 5. Just test whether the throttle valve is smooth in air intake.
