What Causes Engine Shaking and Stalling After Ignition?
1 Answers
Engine shaking can be attributed to the following reasons: Engine Misfire: An engine misfire primarily refers to one or more cylinders not functioning properly. This is typically manifested by noticeable intermittency in the exhaust gas flow, severe shaking of the exhaust pipe, and a distinct sensation of engine vibration, 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 frame. Their purpose is to reduce vibration and provide cushioning during engine operation, as well as to secure the engine in place. Once these mounts become worn or loose, the engine's shaking will become significantly more pronounced. Replacing the engine mounts can greatly alleviate this issue. Carbon Buildup: Vehicles inevitably face carbon buildup issues, which include carbon deposits in the cylinders, throttle body, spark plugs, and intake system. When excessive carbon accumulates inside the engine, the vehicle's ignition energy, air intake efficiency, and air-fuel mixture ratio are affected, 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 to address this problem.
