What Causes Car Body Shaking During Acceleration?

[RhettDella]

The reasons for car body shaking during acceleration include the following: 1. The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injectors is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This causes the combustible mixture to fluctuate between lean and rich, leading to idle shaking after a cold start. 2. Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance in the ignition system or weak spark plug firing can also cause such issues. 3. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can also lead to car body shaking. 4. Car shaking can be related to the aging of engine mounts (also known as engine mounts or rubber mounts). Engine mounts act as the shock absorption system for the engine, absorbing minor vibrations during operation. If the engine mounts fail, these vibrations can transfer to the steering wheel and the cabin, causing shaking during idle.
