14 what should I do if the Mai Rui Bao fault light is on?

If the vehicle has engine trouble, the light is on and the engine is shaking, it means that the mixture of the engine has not reached the ideal air-fuel ratio. Fault codes in the engine system can be detected by special testing instruments, and maintenance and investigation can be carried out according to the contents stored in the fault.

The simplest method is to detect the fault code in the engine system through special detection instruments, and carry out maintenance and investigation according to the contents of fault storage. The common reasons for this phenomenon are: 1, spark plugs that have not been replaced for a long time, too large gap or carbon deposition, resulting in internal damage. 2. The ignition coil of one of the cylinders is damaged, resulting in the cylinder not working normally. 3. The internal short circuit of the gasoline pump makes the low-pressure fuel unable to reach the supply gasoline pressure normally, which leads to engine jitter or flameout. 4. The engine air intake system leaks air, causing the engine to shake; 5. There is too much carbon deposit on the top of throttle, valve and piston under the condition of cold car; 6, one of the engine cylinders, because the valve port is not tightly sealed or the piston ring is stuck by carbon deposition, there is no cylinder pressure, resulting in engine jitter.
