What Causes Engine Shaking During Operation?

[McJameson]

Engine shaking during operation can be attributed to cylinder misfire, worn or loose engine mounts, among other factors. Details are as follows: Cylinder Misfire: Cylinder misfire primarily refers to one or more cylinders not functioning properly, typically manifested by intermittent exhaust gas flow with noticeable shaking of the exhaust pipe. The engine vibration is distinctly felt, sometimes accompanied by a sputtering sound. This is often related to ignition coil failure. Worn or Loose Engine Mounts: Engine mounts are rubber blocks placed between the engine and the vehicle frame. Their purpose is to reduce vibration and absorb shocks during engine operation while securing the engine in place. Once these mounts become worn or loose, engine shaking intensifies significantly. Replacing the mounts can greatly alleviate this issue. Carbon Buildup: Carbon buildup is an inevitable issue in vehicles, including deposits in cylinders, throttle bodies, spark plugs, and intake systems. Excessive carbon buildup inside the engine affects ignition energy, intake efficiency, and air-fuel mixture ratios, leading to unstable power output. Both idling and acceleration may exhibit shaking symptoms. It is recommended to visit a 4S dealership for an engine cleaning service.
