What is the reason for the jitter fault light of Mercedes-Benz c260l engine?

The causes of body vibration when the engine fault indicator light is on are: 1, cold start: insufficient fuel combustion will lead to body vibration during cold start. When the ignition energy is low, especially when the temperature of fuel and lubricating oil is low, more oil is needed to meet the power. 2. Shock absorption system: Body shake is related to the aging of shock absorption system. Mainly responsible for filtering out the vibration when the engine is running. If there is something wrong with the shock absorber, these vibrations will be directly transmitted to the steering wheel and cab, which will affect driving. 3. Tires: When replacing new tires and rims, the wheels should be balanced, otherwise the steering wheel will shake easily when the counterweight is uneven. If it is found that the tire weight is uneven, it is necessary to increase the tire weight on both sides of the lead block inside the steel ring. 4. Throttle: The most common reason for car jitter is that the throttle is too dirty and the fuel injector has too much carbon deposit. After the car runs for a kilometer, the dirty throttle will cause the throttle to close loosely or be stuck by the motor, which will lead to the high idle speed of the engine. 5. Unstable oil pressure: If the oil supply pressure of the oil pump is abnormal, the intake pressure sensor has wrong value and works improperly, the engine body will shake.
