Why did Chang 'an Star stall as soon as it accelerated?

This problem is mainly because the air-fuel ratio does not meet the requirements, that is, there is no problem with the ignition system. The problem is that there is too much air intake and not enough fuel injection during acceleration, resulting in a lean mixture. You can check whether the fuel filter blocks the fuel pressure regulator. The failure of the computer itself may also cause the fuel injection to fail to keep up, and it is not necessary to change the throttle valve to determine whether there is a problem with the throttle circuit. It is best to use diagnostic tools to detect fault codes. If there is no fault code, the fuel filter is mostly blocked.
