What causes the cold car to stall easily?

The most common reason why cold cars are prone to flameout is that the throttle is too dirty or the injector has too much carbon deposit. Too much carbon deposition will cause the car to stall for no reason, or even stall at idle speed after starting, indicating that carbon deposition is already very serious.

The reason why the cold car is easy to stall is that the engine oil is too poor to reach the corresponding calorific value. Low ignition energy, excessive spark plug gap, aging of ignition coil, aging of spark plug high voltage line or leakage. Poor combustion, water temperature sensor failure, dirty air flow meter, resulting in reduced air intake. The exhaust gas recirculation valve is in poor working condition, and the exhaust gas is introduced at idle speed.

After the car starts, it should be warmed up for a period of time according to the local temperature. It is best to wait until the idle speed is basically normal or the water temperature comes up before driving slowly. When the throttle is dirty, the most obvious performance is that when the car refuels, it will feel that the throttle is stuck heavily and the speed will be slow. And when you step on the accelerator at idle speed, the speed will rise slowly and the response will be slow. Release the throttle and the speed will drop immediately. In addition, it will directly affect the accuracy and smoothness of engine intake, resulting in idling jitter and even flameout. (Photo/Text/Photo: Chen Min 2) @20 19
