1. Air intake pipe leakage: Under normal circumstances, the intake volume must be strictly limited., if the air intake pipe leaks and the air flow sensor cannot measure the real air intake, then the electronic control unit inaccurately controls the air intake, resulting in unstable idling of the car.
2. The sudden high and low idle speed may be caused by the following reasons: idle control valve failure: the normal idle speed of the electric injection engine is determined by the idle speed control valve.
3. The reasons are as follows: the stolen goods produced in the air and the oil sludge generated by gasoline, etc., are easy to cause the vehicle throttle valve to be too dirty and the idle motor does not work smoothly. Too much carbon accumulation is easy to cause the valve closure to be loose, the fuel injection nozzle is not atomized well, and the combustion is insufficient. The exhaust pipe is blocked, resulting in poor exhaust.
4. The following are the specific reasons for the unstable idle speed of the car: air intake manifold leakage: when the air, gasoline steam and combustion exhaust gas that should not enter the intake manifold, the mixed gas is too thick or too thin, resulting in unstable idling of the car.
5. The reason for the sudden idling speed of the car may be: too much carbon accumulation in the throttle valve. Inlet manifold or various valve leakage.
1. Engine cylinder deficiency: Engine cylinder deficiency mainly refers to the abnormal operation of one or more cylinders of the engine, which is generally manifested as: the exhaust gas flowing out of the car is obviously intermittent, the exhaust pipe shakes violently, and the engine shaking can be obviously felt, sometimes accompanied by abnormal noise. This is mostly related to the failure of the ignition coil.
2. The sensor is not working or fails. The sensor is the sensory nerve of the car brain ECU, which can sense effective signals.If it is a stutter caused by a gearbox problem, it is recommended to go to a professional repair shop or 4S store to test the gearbox control system.
3. Leakage in the air intake system or vacuum system. The air filter is blocked. The idle control valve or additional air valve is not working wel. The air flow meter is faulty. The EGR valve is stuck and open and cannot be closed. Improper idling adjustment. The pressure of the oil road is too low. Poor atomization, oil leakage or blockage of the fuel injector. The spark plug is defective.
1. Water temperature sensor failure: When the engine idles, the car The electronic control unit will judge the thermal state of the engine according to the signal input by the coolant temperature sensor, that is, the water temperature sensor, and correct the fuel injection volume. If the water temperature sensor is poor, the output signal is not accurate, resulting in too low idle speed, lack of fire and slow operation.
2. The sudden high and low idle speed may be caused by the following reasons: idle control valve failure: the normal idle speed of the electric injection engine is determined by the idle speed control valve.
3. The reason for the high and low idling speed of the car may be: excessive carbon accumulation in the throttle valve.Inlet manifold or various valve leakage.
4. The following are the specific reasons for the unstable idle speed of the car: air intake manifold leakage: when the air, gasoline steam and combustion exhaust gas that should not enter the intake manifold, the mixed gas is too thick or too thin, resulting in unstable idling of the car.
1. Air flow sensor problem; intake manifold leakage; carbon tank solenoid valve is often open; crankcase forced ventilation valve is often open; air filtration blockage. The reasons for the high and low idling speed of the car may be: excessive carbon accumulation of the throttle valve, the leakage of the intake manifold or various valves.
2. The sudden high and low idle speed may be caused by the following reasons: idle control valve failure: the normal idle speed of the electric injection engine is determined by the idle speed control valve.
3. The reasons for the high and low idling speed of the car may be: excessive carbon accumulation in the throttle valve, the intake manifold or various valve leakage.
4. The reason for the high and low idle speed of the car may be: too much carbon accumulation in the throttle valve. Inlet manifold or various valve leakage.
5. High idle speed and low idle speed may be caused by the following reasons: Idle control valve failure: The normal idle speed of the electric injection engine is determined by the idle speed control valve.
Idling unstable, high and low solution: Change oil: When there is a problem with the idling speed of the vehicle, we should first check whether it is time to change the oil. If you replace it, otherwise the engine will be abnormal after a long time.
Solution; the best way is to clean the oil line, clean it regularly, and use PNF original liquid fuel additives to solve the above problems caused by carbon accumulation.
The solution to the unstable idle speed of the car is to adjust the throttle and idle speed to make the engine run at the lowest stable speed. The throttle valve is a controllable valve used to regulate the air entering the engine.
The reasons for the unstable idling speed of the car are: blockage of the idling air measurement hole, poor operation of the idling device, weak sparks of individual cylinder spark plugs, loose sealing of individual valves, leakage of air intake manifolds, premature or too late ignition time, improper idling adjustment, etc.
