There is too much idle air in Liu Ma.

Excuse me, do you want to ask "the reason for the large idle air flow in Liu Ma"? The reasons for such a large flow are as follows:

1. Dirty air filter: The function of air filter is to filter dust and impurities in the air and prevent them from entering the engine. If the air filter is dirty, it will affect the normal work of the air flowmeter, resulting in a large flow at idle speed.

2. Throttle carbon deposit: Throttle is the valve that controls air to enter the engine. If the carbon deposition on the throttle is serious, it will affect its opening and the measurement accuracy of the air flowmeter, resulting in a large flow at idle speed.

3. Air flowmeter failure: Air flowmeter is an important component for measuring air flow. If it fails, it will affect the air flow measurement at idle speed, resulting in large flow.

4. Air leakage in the air intake system: If the air intake system leaks, the flow measured by the air flowmeter will be inaccurate, resulting in a large flow at idle speed.
