Chery A5 cold car is difficult to start. What's wrong with spraying detergent before the accelerator starts?

It means that the fuel injection of your car is too small. There are several reasons. One is caused by the pressure relief of the gasoline pump, because the gasoline pressure is too low due to long-term parking at night. One is that the water temperature sensor is broken, and the signal fed back to the automobile ECU is inaccurate, resulting in too little fuel injection. One is that the injector is too dirty, and the amount of gasoline sprayed is too small, so you can rule it out one by one.
