How to solve the starting jitter of Fox cold car (the jitter of classic Fox cold car is normal for hot car)

It's caused by dirty throttle. It is recommended to go to the repair shop for cleaning. Because Fox is an electronic throttle structure, if there is colloidal carbon deposit near the throttle valve plate, the cross-sectional area of the air passage will change when the control unit adjusts, resulting in the control unit not being able to accurately control the idle intake, resulting in the mixture being too rich or too thin.

Solution:

1. No matter whether it is a cold start or a pause before starting, it is usually a few minutes after the power is cut off, and every start-up should be powered on for 3-5 seconds, so that the fuel pump can supply oil first, let the fuel pump pressure go up, and then ignite after all sensors have signals.

If you stay for more than an hour, you'd better not leave. In-situ heating 10-30 seconds will not waste too much oil.

3. Especially if you suddenly enter the service area after driving at high speed, don't turn off the engine immediately. First open the door and get off, turn off the headlights at night, and then check the internal equipment of the vehicle, such as the glass is turned off and the lights are turned off, that is, turn off the engine after idling 10-30 seconds.

4. There is no problem in the self-inspection, but the engine and gearbox are not lubricated well after ignition, and there will still be wear when walking. It is best to heat in situ for 1-2 minutes.
