What Causes the Mercedes-Benz E300 to Shake During Acceleration?

[DeAvery]

Mercedes-Benz E300 shaking during acceleration may be due to excessive carbon buildup. General symptoms of abnormal shaking: Fault-induced shaking, such as poor cylinder operation or air leakage, is a very noticeable phenomenon. Normal shaking is relatively uniform, and sitting inside the car, it is barely perceptible, with normal acceleration. Reasons for abnormal shaking during driving: Excessive carbon buildup: If there is severe carbon buildup in the engine cylinders, it can lead to clogged spark plugs and valves, directly causing the car to shake at idle. If the vehicle's acceleration performance has significantly declined and the shaking persists for a long time, consider an engine cylinder cleaning. Fuel system malfunction: Unstable fuel pressure can easily cause inconsistent mixture concentration, leading not only to shaking but also to unstable idle conditions. First, consider replacing the fuel filter, as prolonged use may cause the filter element to clog. Then, check the fuel pressure bypassing the fuel filter. If abnormal, it may indicate an issue with the fuel pump.
