What is the reason for the large throttle opening?

About the landlord's concern about "what is the reason for the large throttle opening?" The following is my personal opinion:

The large throttle opening is generally caused by excessive carbon deposition in the throttle. Excessive carbon deposition will lead to engine idling and flameout. How to clean the throttle:

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. Million car purchase subsidy
