What should we do if the air fuel ratio of the car is incorrect?
The first is that the air inlet is blocked by the air filter fouling, which causes the intake air to decrease and the mixture is too rich; Second, the oil nozzle is worn. It can not be closed when it should be closed. There is oil dripping and the mixture is too rich; The third is the failure of the oil pressure regulating valve, which causes the system oil pressure to be too high, the same nozzle intake air leaks or is not smooth, the fuel pressure is insufficient, the fuel injection nozzle works poorly, the ignition performance is low, the gasoline quality is poor, the oxygen sensor cannot detect accurately, the air flow meter is too dirty or fails, and there are many possibilities under the three-way catalytic performance, most of which cause the poor fuel quality.
