What is the automatic flameout at idle speed of Mai Rui Bao xl?

Chevrolet Mai Rui Bao XL (view the transaction price | model details) automatically shuts down at idle speed, mostly due to the throttle and idle motor. Serious carbon deposition or parts damage at the throttle idle motor may lead to this failure, and insufficient air intake is the main reason. At the same time, check the air cleaner element, intake air flow sensor, intake air pressure sensor and throttle position sensor.

There are many reasons for the idling flameout of Chevrolet Mai Rui Bao xl. First of all, analyze the symptoms of idling flameout. If the engine flameout occurs after entering normal idle operation, there are generally the following reasons leading to this failure: the engine idle motor or the idle motor circuit is damaged; Brake vacuum booster vacuum tube leaks; Brake vacuum booster membrane is damaged; Air leakage in the intake manifold; There is a problem with the idle speed control module in the engine electronic control unit (ECU).

What shall we call it if the engine sometimes turns off at idle speed and is normal after restarting? Intermittent idling flameout is difficult to find in the actual maintenance process, and there are many reasons for this kind of thing, and all kinds of parts or lines are not completely damaged. What is more troublesome is that the engine can return to normal after being restarted occasionally, so even if the engine is idling due to the sensor, the engine electronic control unit will think that this phenomenon is not a fault and will not be recorded by the engine electronic control unit, so it is impossible to obtain information about the fault from the fault diagnosis system of the engine electronic control unit.

Generally speaking, there is no harm in turning off the engine, because when the engine is idling, the vehicle often stops. If the vehicle idles when taxiing, corresponding measures can be taken to avoid danger because it is far away from the obstacles in front. Of course, if you happen to turn off the engine when braking suddenly, it will be very harmful, because once the engine is turned off, the brake vacuum booster will not work, which will greatly reduce the braking efficiency of the vehicle, and the direction assist device will also fail, making the vehicle turn very heavy. If you add panic, you should pay special attention.
