What Causes Vehicle Body Shaking at Low Speeds?

[VanEverly]

Vehicle body shaking at low speeds is caused by: 1. Wheel dynamic imbalance issues; 2. Hydraulic power unit imbalance. Slight vibration during low-speed driving is quite normal and can be improved by partially depressing the clutch. However, if the shaking is severe, it's necessary to inspect the ignition and fuel systems or clean the intake system. The throttle valve, which controls air intake into the engine, comes in two types: traditional cable-operated and electronic throttle. After entering the intake manifold, air mixes with gasoline to form combustible mixture for engine combustion. Connected to the air filter above and engine block below, the throttle valve is often referred to as the 'throat' of an automobile engine.
