What should I do if the free ship suddenly shuts down while driving?

Hello: According to the above vehicle usage and vehicle failures, it is suggested to go to the repair shop to check the air intake system to see if there is any cause of colloidal carbon deposition, otherwise it can be eliminated by cleaning. Because there is colloidal carbon deposit in the throttle and the accessories of the idle motor, the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle intake, resulting in the mixture being too rich or too thin. Therefore, ecm repeatedly adjusts the idle speed to reach the standard value, which causes you to "run off" and stall.
