What if Yida's car suddenly stalls in neutral?

For the above-mentioned vehicle use phenomenon, this fault is due to the unclean throttle, that is, there is a large amount of colloidal carbon deposited on the throttle valve plate, while Yida vehicle belongs to the electronic throttle structure, and its auxiliary air is reasonably adjusted by the throttle valve plate driven by the throttle motor. If there is too much carbon and dirt accumulated in the throttle and the surrounding intake port, the cross-sectional area of the intake port changes, which makes the control unit unable to accurately control the idle intake air volume, resulting in the mixture being too rich or too lean. Therefore, ecm repeatedly adjusts the idle speed to reach the standard value, which causes you to "run off" and stall. Maintenance method: go to the repair shop for cleaning, and then match the idle speed.
