What is the high air flow of Mai Rui Bao?

Throttle failure, air filter blockage, air flow sensor failure. Reasons for the large air volume of Mai Rui Bao:

1. The throttle valve is not completely sealed, resulting in air leakage at the front end of the throttle valve, which in turn leads to high air flow of Mai Rui Bao.

2. The air filter is blocked, resulting in insufficient air flow and unstable engine operation, which in turn leads to high air flow of Mai Rui Bao.

3. The air flow sensor is out of order, which makes the engine control unit unable to accurately measure the air flow, thus making Mai Rui Bao's air flow high.
