The reason why the throttle opening is too small

The reason why the throttle opening is too small is that the throttle opening is too large. Generally, only when there is too much carbon deposit will the throttle be opened. Excessive carbon deposition will cause the engine to stall at idle speed. Method of cleaning throttle valve: 1. Clean the sludge in the throttle body with carburetor cleaner, especially around the throttle. Excessive sludge will fill the gap of the valve in the throttle body; 2. Then spray the telescopic rod of the idle motor with carburetor cleaner, then scrub the sludge with cloth to expose the metallic luster, and wash the sludge exposed by the motor shaft together; After careful cleaning, a bucket of cleaning agent is almost used up. At this time, the throttle body is already very clean. Carefully replace the three electronic devices, wash off some oil stains outside with the remaining cleaning agent, and replace the throttle body as it is; 4. Remember to connect the three electronic devices on the throttle body, otherwise the computer will automatically give an alarm when the key is turned on during the final test. @20 19
