Volkswagen Zhijun leaves in the morning. Why does the engine get stuck for a while before idling normally?

When Volkswagen Zhijun started the engine in the morning, the throttle of the vehicle was dirty, which made it difficult to open the throttle plate easily. When the vehicle is idling, a large amount of fuel is injected, and the throttle cannot be fully opened to provide enough air intake, so the engine is abrupt and can only be solved by cleaning the throttle. The specific operation steps are as follows:

1. Loosen the thin tube clamp connected to the throttle.

2. Loosen the throttle clamp.

3. Pull off the throttle connecting hose.

4. Use special throttle cleaner to spray and clean the inside of the throttle.

5. After cleaning, replace the connecting hose.
