Why does a car shake while driving?

[EverettFitz]

Here is the relevant introduction about car shaking during driving: 1. Dirty throttle valve: The most common cause of car shaking is a dirty throttle valve or excessive carbon deposits in the fuel injector. 2. Tire issues: If the car shakes during high-speed driving, check the tires, steel rims, and drive shaft. 3. Steering ball joint: If shaking occurs when pressing the brake pedal, inspect the steering ball joint, tie rod, steering gear, and other connecting components of the steering system. 4. Engine mount aging: Car shaking can also be related to aging engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during engine operation. If the engine mounts are faulty, these vibrations will be transmitted to the steering wheel and the cabin, causing shaking at idle speed.
