What are the reasons why the Changhe Furuida M50 sometimes fails to accelerate?
2 Answers
Changhe Furuida M50 sometimes fails to accelerate due to reasons such as the car not starting, unstable idle speed, fluctuating RPM, and abnormal fuel supply. Car not starting: The car battery voltage is low. The specific detection method is to test the battery voltage with a multimeter in voltage mode. If it is below 10V, it needs to be replaced. Unstable idle speed: Check if it is caused by carbon buildup, focusing on inspecting and cleaning the throttle body. Fluctuating RPM: It is necessary to inspect, test, and replace the spark plugs. Abnormal fuel supply: Confirm the quality of the gasoline being used. Test and inspect components related to the starting and fuel supply system, such as the starter, fuel pump, and sensors.
I remember repairing many Changhe Furuida M50 vehicles, and the reasons for the inability to accelerate are varied, mostly due to issues in the fuel system. The fuel pump can wear out and age after being submerged in the fuel tank for a long time, leading to insufficient fuel supply and difficulty in accelerating, especially after long-distance high-speed driving. Once, a car owner complained about lack of power when climbing hills, and upon inspection, it was found that the fuel injector was clogged with impurities, preventing it from spraying enough fuel. Faulty sensors, such as the air flow meter, can also cause the ECU to receive incorrect signals, leading to inaccurate control. Poor fuel quality can contribute to this problem as well, with PetroChina and Sinopec fuels having fewer impurities. For safety, it's best to slow down and pull over if this occurs, as forcing the car to continue can lead to stalling or breakdowns. It's recommended to visit a professional shop as soon as possible to test fuel pressure and conduct a thorough inspection.
