What is the reason for the idling jitter of Mercedes-Benz c260 new car?

The reason of idling jitter of Mercedes-Benz c260 new car is that the throttle is too dirty and some parts of the vehicle have problems. The following is a detailed introduction and solution: 1, the throttle is too dirty: solution: clean the oil circuit, throttle and nozzle. In the case of cold car, the carbon deposit will adsorb some fuel. If the fuel does not completely enter the cylinder for combustion, it will cause the symptoms of unstable idle speed and difficult start. 2. Slight lateral overturning motion of the engine gearbox: Solution: Because the axial direction of the half shaft has a certain included angle with the axial direction of the inner cage, during the rotation of the cage, this stress point changes back and forth along the axial direction to replace the damaged inner cage or half shaft. 3. Ignition system failure: Solution: If the ignition system fails, it is necessary to check the spark plug, cylinder line, ignition coil, cylinder line leakage and carbon deposition in the spark plug, which will cause jitter and can be solved by replacement.
