What's the matter with the cold start jitter and flameout of Roewe rx5?

Causes of cold start jitter and flameout of Roewe rx5 in Pacific Auto Network: 1, throttle blockage, carbon deposition and abnormal opening; 2. Carbon deposition and blockage of the fuel injector; 3. The spark plug is burnt or damaged; 4. Use inferior gasoline.

There are many reasons for flameout, one is circuit failure. This may be a low-voltage power failure and flameout during driving. At this time, you can mainly check the ignition and starter switches and fuse boxes. Short circuit of low voltage line leads to flameout, which is intermittent in this case.

Check the low voltage line. One is equipment failure. This problem is generally ignition coil, capacitor and electronic ignition module. That is to say, it can be started at first, turned off after a while, and then turned off again. There is also an oil circuit fault. The gasoline pump is damaged, the oil pipe is broken, the oil inlet is blocked, and the oil tank is out of oil. But in this case, the car can be restarted, but it is difficult. Because you can't see the real car, you can't accurately judge the fault. It is recommended to contact the local 4S shop for inspection and maintenance.

If the engine sometimes shuts down at idle speed, and it is normal after restarting, it is called "intermittent idle flameout". The reasons for "intermittent idle flameout" are generally: the engine idle motor is stuck; The wire sheath of idle motor is somewhat worn; Idle air hole is too dirty; There is something wrong with the engine throttle position sensor; There is a problem with the camshaft position sensor or crankshaft position sensor; Engine speed sensor is faulty or too dirty; There is something wrong with the idling control program of the engine electronic control unit, and so on. In addition, if there is a problem with the quality of gasoline, it will also cause this failure.
