Does the throttle need cleaning?

The throttle valve needs cleaning, and the cleaning cycle of the throttle valve is about 20,000 ~ 30,000 kilometers. Steps for cleaning the throttle: 1. Open the hood of the car. At the joint of a black trachea, there is a metal part with a metal hoop on it, which is a throttle valve; 2. Unscrew the metal hoop on the throttle with a screwdriver. There is no need to unscrew it completely. As long as it is loose enough, the next step is to remove the plastic pipe connected to the throttle joint. 3. After removing the throttle, you can see the inside of the throttle, which is full of oil stains and carbon deposits. Take out the accelerator cleaner and spray it a few times on the inside of the accelerator, and you can see that all the oil stains and carbon deposits have melted; 4. Then clean it with toilet paper, then push the movable baffle in the accelerator with your fingers or other objects, spray it a few times, and then clean it with toilet paper; After cleaning, you can put it back in the original way, start the car, let the engine turn for a while, and discharge the dirty things in the throttle.
