There was a loud noise when the car was idling, and the throttle was gone after a little refueling?

There is abnormal noise when the car is idling, which may be caused by broken teeth or surface damage of the driving wheel. At this time, it is necessary to check whether the gear is damaged and replace it with a new gear in time.

It may also be the abnormal sound caused by the looseness of the connecting rod parts of the wheel. There are many gears in the transmission of the wheel. If it is too loose, it will make noise when turning.

Many parts are cold and hard, and the lubrication degree is not enough, which leads to abnormal noise. At the same time, when the driving wheel slips, it can't refuel violently, which causes the planetary gear to bite on its shaft.

The car is in the running-in period, and the differential planetary gear and the half-shaft gear are not matched, so it takes a period of running-in period and abnormal noise occurs.

If the idle speed of the engine is unstable, the idle speed is shaking or the idle speed is too high or too low, please do not drive reluctantly, and check the technical condition of the vehicle in time to avoid the failure of flameout while driving.

Idle speed adjustment must be carried out under normal conditions, such as normal engine temperature, proper valve clearance, normal ignition system, good sealing of all pipelines, full throttle opening and tight throttle closing. When adjusting, first loosen the throttle opening adjustment screw to make the engine reach the lowest stable speed.
