What happened to Lingpai engine jitter and throttle flameout?

The reasons for the engine jitter and the closing of the fuel inlet door of the Lingpai engine in Pacific Auto Network are: 1, the throttle valve is dirty, and the throttle opening of the automobile will be reduced or stuck, or even closed; 2. The ignition coil is damaged and the coil is open or short-circuited; 3. The gasoline filter is too dirty; 4. The air flow meter is damaged; 5. When the car is running, the oil pump can't keep the oil pressure or the oil injection quantity is insufficient, which leads to flameout when accelerating.

Honda Lingpai idling flameout reason: the rubber ring of fuel pressure reducing valve is not installed in place; EGR valve is stuck; The engine air flow sensor (MAF) is faulty.

A Guangqi Honda Lingpai sedan with a mileage of about 60,000 km, model code GJ5 and engine model R 18Z5. User feedback: the car will turn off immediately after starting. Inspection and analysis: after receiving the car, the maintenance personnel should first confirm that the fault phenomenon is consistent with the user's description. Because the car has just replaced the fuel filter in our shop, the maintenance personnel removed the fuel filter first to be on the safe side, and found nothing unusual. At the same time, the oil pressure was tested, which was normal. According to the previous maintenance experience, the reasons for this failure may be: the rubber ring of fuel pressure reducing valve is not installed in place; EGR valve is stuck; The engine air flow sensor (MAF) is faulty. Because the fuel filter has just been replaced and the relevant accessories have been carefully checked, the problem of the fuel pressure reducing valve should be ruled out. Then, the EGR valve was removed for inspection, and no blockage was found. After cleaning and loading again, the fault still exists. Finally, MAF left. After removing the air filter element, it was found that the filter element was not the original accessory, and the surface of the filter element was dirty, and even holes appeared in some places. When the scan tool is connected to check the data flow, it is found that the MAF sensor data is abnormal. When MAF was taken out, it was found that there was a foreign body stuck in it, which led to abnormal data.
