What happened when the cold car turned off a few seconds after it started?

The reason for carbon deposition is that the cold car of Pacific Auto Network started to shake a few times and then turned off. 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 lead to insufficient air intake, difficult starting or easy flameout at idle speed. After the water temperature reaches the normal working temperature of the engine, the computer will adjust the position of the throttle valve plate after the throttle valve is opened too much, resulting in high and low idle speed. The problem of cold car start-up and flameout involves many aspects The following are some reasons that will be encountered in daily car use: 1, oil problem, which is often encountered in car maintenance and the easiest to check. Change the oil model or try to refuel elsewhere. 2. Too much carbon deposit on the accelerator is also the main reason for the unstable idle speed and flameout of the car. Go to a professional repair shop or 4S shop to clean the throttle. 3, gasoline pump pressure is low or failure is easy to out of the oil and cause flameout. 4, because the vehicle has been parked for a long time and the engine oil is sticky, this phenomenon is not a big problem, and it can be warmed up after the fire.
