The car will automatically turn off when it is ignited, saying that it is good for oiling your feet. What inspection should be done in this case?

This is a typical idle speed control problem! The main reasons are: the initial setting of idle throttle drift; Idle throttle opening is small. Adjust the idle throttle opening, adjust the screw and adjust the throttle opening.

Throttle body oil blocks the idle air metering hole; The air filter is invalid, and the poor ventilation of the crankcase leads to too much throttle oil/carbon deposit, which leads to the reduction of idle intake air. Check/replace the air filter and clean the throttle. ECU idling control is elegant. Flash the ECU once (both the first time and the second time are acceptable). The battery voltage is too low and the ignition energy is insufficient. It is generally not recommended that you do not have a diagnostic instrument. It is best to find a professional maintenance organization for maintenance. Check whether there is carbon deposit on the throttle. If there is too much carbon deposit, the throttle valve needs to be cleaned, but for 4S, it needs to be cleaned regularly, because some vehicles need computer calibration after cleaning.

There are two factors to check whether the spark plug has too much carbon deposit. One is oily (gasoline), and the other is that the spark plug needs to be replaced. If there is something wrong with the gasoline filter, it is not expensive to replace it directly. You can use a professional computer to check whether there is a problem with the engine sensor and whether the gasoline pressure is normal. This phenomenon often happens in my own car. Either the idle speed is unstable and shivering, or the throttle is not given. Clean the throttle every time. Generally speaking, when we start the engine, we don't need an air valve. Throttle closed. When the engine is started, air must enter the cylinder and mix with fuel before it can be ignited by the spark plug.

When the throttle valve has too much carbon deposit, the bypass valve is blocked and air cannot enter the cylinder. If there is no air in the cylinder, how can the fuel burn? This car must be broken. At this time, when you step on the gas pedal, the computer will instruct the gas pedal to open, and the air will enter the cylinder from the gas pedal, mix with the fuel and burn, and the engine will start. This is the main reason why the engine starts with the throttle. If there is something wrong with the spark plug, or the cylinder pressure is not reached, or individual cylinders are not working, it may be necessary to step on the accelerator to start the engine.
