What Causes Low-Speed Shaking in Mercedes-Benz?

[LeilaLee]

Reasons for low-speed shaking in Mercedes-Benz: Poor fuel combustion resulting in insufficient power output; possibly due to spark plug failure causing inadequate ignition energy; air intake system leaks or low fuel pressure; injector poor atomization, leakage, or blockage; improper idle adjustment and other faults. Low-speed shaking is the most common fault: It is caused by damaged spark plugs where the electrode gap wear leads to insufficient spark plug ignition energy, causing unburned air-fuel mixture and shaking during acceleration. Another reason is cracks in the ceramic part of the spark plug, leading to no ignition in one cylinder, which also causes acceleration shaking. Preventing idle shaking: First, determine whether the shaking is caused by carbon deposits. If it is, clean the carbon deposits. If the shaking persists after cleaning, check the spark plugs. Therefore, regular car maintenance is essential. Idle shaking issues can also be identified and resolved during the maintenance process.
