What is the reason for the low-speed jitter flameout of Beiqi Wangwei M20? Beiqi Wangwei Beiqi Wangwei M20 (view the transaction price | detailed description of the vehicle) What is the reason for the low-speed jitter flameout? Because the throttle is too dirty, the throttle will not close tightly or the idle stepper motor will be stuck, which will lead to excessive idle speed of the engine, and the carbon deposit generated during the engine work will also lead to vehicle jitter, especially when the vehicle is started, the engine jitter will be more serious than usual, and sometimes it will not be started at one time. Therefore, when the vehicle is shaking, first check the throttle and fuel injector. If the throttle valve is found to be too dirty or the fuel injector has too much carbon deposit, it should be cleaned in time. Car jitter is sometimes related to the aging of engine feet. The engine foot is actually the damping system of the engine. If there is something wrong with the engine foot, it will cause idling jitter. With the opening of the electrical system, the engine will increase the load, leading to idling and slipping. In order to make up for the jitter caused by idling slip, the engine will automatically pull up the speed. When the automobile electrical system is turned on, especially when the automobile air switch is turned on in summer, the engine often shakes. If the jitter at idle speed will not be reduced due to the operation of the vehicle-mounted air compressor, then this jitter is probably caused by the aging of the engine foot and needs to be replaced in time. @20 19
