How to solve the idle problem of BYD f6 washing throttle?

Loosen the air inlet hose clamp behind the air flow meter, so that a large amount of air leaks between the air inlet hose and the air flow meter.

Because the mixture is too thin, the idle speed will be low. There are many common reasons for the low idle speed of the car, such as improper cleaning of the throttle, which leads to the failure of the stepping motor.

When the car is cold started, it is normal for the engine to idle at a high speed. The engine needs a high speed to make the engine reach the normal working state as soon as possible, and it needs a rich mixture, so the air intake and fuel injection will increase, resulting in a high speed.
