What Causes a Mercedes-Benz to Shake?

[MacIvan]

Here are the possible reasons for a Mercedes-Benz shaking: 1. Worn or loose engine mounts: Engine mounts are rubber blocks placed between the engine and the frame. Their purpose is to reduce vibrations and absorb shocks during engine operation while securing the engine in place. If these mounts become worn or loose, engine shaking will become noticeably severe. 2. Engine misfire: An engine misfire occurs when one or more cylinders fail to function properly. Common symptoms include intermittent exhaust flow, severe shaking of the exhaust pipe, noticeable engine vibrations, and sometimes accompanied by a sputtering sound. This is often related to faulty ignition coils. 3. Carbon buildup in the engine: Carbon deposits can accumulate in various parts such as the cylinders, throttle body, spark plugs, and intake system—all of which are critical to the engine's power output. Excessive carbon buildup reduces ignition efficiency and intake performance, ultimately leading to engine shaking and sluggish acceleration.
