Do you know that the idle speed of Ford Mondeo is unstable?

1, Ford Mondeo wins unstable idle speed, generally because there are too many scales on the throttle valve and air intake, which will lead to the change of the cross-sectional area of the air passage, making it impossible for the control unit to accurately control the idle intake, resulting in the mixture being too rich or too lean, which will lead to abnormal combustion and jitter.

2. The spark plugs caused by individual spark plug failures are too weak, which will affect the performance of the car, leading to the symptoms of "fire" and unstable idle speed.

3, fuel pressure failure, if the oil pressure is too low, it will lead to the fuel sprayed by the injector in a bad atomization state, or the sprayed fuel is linear, in severe cases, only oil droplets will be sprayed, and the reduction of fuel injection will make the mixture too thin, which will happen.
