There is airflow noise after the throttle valve is cleaned.

Clean the throttle in the afternoon. After cleaning, the engine fault light comes on. There is a sound of air flow at the throttle, like air leakage. Has this ever happened to you?

The problem has been solved. It turned out that a sealing ring of the injector was broken, which led to air leakage in that place. It has been solved. Now the car has just changed Total 7000 oil, air conditioner filter, oil filter, gasoline filter, throttle cleaning and fuel injector. I feel that the sound of the car has become smaller and the acceleration is slightly better. Observe fuel consumption.
