[OBennett]

Mercedes-Benz C260 new car idle vibration is caused by a dirty throttle, and some parts of the vehicle malfunctioning. Below are detailed explanations and solutions: Dirty throttle: The solution is to clean the fuel system, throttle, and fuel injectors. In cold conditions, carbon deposits can absorb some fuel, and if the fuel does not completely enter the cylinder for combustion, it can lead to unstable idling and difficulty starting. Slight lateral tilting of the engine transmission: The solution is to replace the damaged inner CV joint or axle shaft, as there is a certain angle between the axial direction of the axle shaft and the inner CV joint, causing the force point to continuously change along the axial direction during rotation. Ignition system failure: The solution is to inspect the spark plugs, ignition wires, and ignition coils. Typically, leakage in the ignition wires or carbon buildup on the spark plugs can cause vibration, which can be resolved by replacement.
