What Causes Vehicle Body Shaking While Driving?

[LukeAnn]

Here are the reasons for vehicle body shaking while driving: 1. Excessive carbon buildup on the fuel injectors and throttle body, or a dirty throttle body. During cold starts, carbon deposits inside the engine absorb some gasoline, resulting in an overly lean combustible mixture, making it difficult to start or causing engine shaking. 2. Tire-related issues, requiring inspection of tire pressure, tire wear, shock absorbers, and other components. It is best to perform a four-wheel alignment and dynamic balance. Additional information: The throttle body is a controllable valve that regulates air intake into the engine, available in traditional cable-operated and electronic throttle types. After entering the intake manifold, the air mixes with gasoline to form a combustible mixture for combustion and power generation. It connects to the air filter at the top and the engine block at the bottom, often referred to as the throat of the automotive engine.
