What Causes Vehicle Shaking When Turning the Steering Wheel in Place?

[FelicityLee]

If no abnormal fuel consumption is observed, the engine's operation should not have any major issues. The shaking of the steering wheel is likely caused by engine vibrations, which also occur during idling. Below are the specific reasons for this phenomenon: Dirty Throttle Body: The most common cause is a dirty or malfunctioning throttle body, which can lead to idle shaking. The primary reason for a dirty throttle body is the accumulation of carbon deposits at the junction of the throttle valve plate's shaft and the throttle body, resulting in imprecise throttle opening and causing idle vibrations. Spark Plug Misfire: If a spark plug fails to ignite, it can cause one or more cylinders to stop working, which also results in idle shaking.
