What is the reason why Chang 'an Yuexiang v3 does not idle during operation?

1, the throttle is dirty. When the cold car starts, the engine has insufficient air intake, resulting in insufficient combustion. After a few seconds, the computer will automatically adjust and it will be fine. 2. The carbon deposit in the intake valve is serious. The oil sprayed by the cold car is sprayed to the intake valve, and most of it is absorbed by the carbon deposit in the valve, resulting in too thin fuel in the cylinder, and then it shakes a few times.

Basically can solve the problem of this car, ask the car master. 4S shop professional technician, 10 minutes to solve.
