Huang Hai Qisheng stepped on the accelerator at idle speed to slow down.
The answer to the question that Huanghai Qisheng's idling speed is slow is as follows: The reason is 1, and the idling motor is out of order; 2, the valve clearance is too large; 3. Excessive carbon deposition in the engine; 4, the throttle line is too astringent; 5. The elasticity of the accelerator pedal spring or throttle spring is insufficient. The slow idle speed drop may be a problem with the water temperature sensor. The function of the water temperature sensor is to detect the temperature of the engine coolant and send the signal to the ECU of the EFI system, and the ECU will adjust the fuel injection quantity according to the temperature of the engine coolant. If the water temperature sensor signal is unstable, it will affect the fuel injection quantity. In the case of idle speed, the fuel injection quantity of the engine is directly affected by the water temperature sensor, and the idle speed of the engine will automatically increase when the water temperature is low. When the water temperature is high, the idle speed of the engine will decrease. Therefore, it is necessary to check the water temperature sensor when the idle speed drops slowly. In addition, problems such as idle speed regulating valve, idle speed motor, intake pressure sensor, oil circuit blockage, nozzle blockage, etc. will also cause idle speed to slow down. Therefore, it is recommended to go to the 4S shop for inspection and maintenance as soon as possible. Another possibility is ignition timing and throttle. First, under the premise of cleaning and adjusting the throttle, it is necessary to check the throttle return. If the throttle valve does not return well, the idle speed will be too high or unstable, such as the performance of the return spring and the clearance of the throttle valve plate, otherwise it will be adjusted or replaced.
