The car stalled after the cold start?

The reason of carbon deposition is the shaking and flameout of the car during cold start. Remove carbon deposits.

Carbon deposition generally appears on the inner wall of throttle valve, intake valve head, intake port, piston top and combustion chamber. Excessive carbon deposition will cause insufficient air intake, difficult starting or easy flameout at idle speed.

After the water temperature reaches the normal working temperature of the engine, the idle speed rises and falls due to the excessive opening of the throttle valve exceeding the normal idle speed value, and the computer repeatedly adjusts the position of the throttle valve plate.

Precautions:

1. First of all, don't start the car in a hurry in winter. You should detour from left front to left back and then to right, then go back to the left front door, make a surface inspection of the whole car, and then prepare to start. When starting, you must step on the clutch pedal to separate the gearbox from the engine and reduce the engine load.

2. Before starting, turn on the ignition switch, wait for about 5 seconds, and let the oil pump work before starting.

3, pay attention to open the door a little, so as to avoid the fog make the front block can't see the road clearly, don't turn on the hot air heater before the temperature comes up, so as not to make the engine warm up for too long.

After starting the engine, it is best to turn on the lights, radios and other electrical equipment. Turn off these power-consuming electrical facilities before parking, and then turn off the engine.
