Why does the car body shake when accelerating?
1 Answers
The reasons for car body shaking when accelerating: 1. Severe engine carbon deposits causing body vibration; Dirty throttle or severe carbon deposits on engine fuel injectors, as the gasoline adsorbed on carbon deposits is sucked into the cylinder for combustion after the car starts, resulting in uneven combustible mixture in the engine and causing idle vibration after startup; 2. Ignition system malfunction: If there are issues with spark plugs, high-voltage wires, or ignition coils, the car body will also shake; 3. Brake disc failure: Deep scratches or grooves on the brake disc; 4. Unstable oil pressure: If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect or malfunctioning, it can also cause body vibration; 5. Aging engine components: Problems with engine parts can transmit vibrations to the steering wheel and cabin, causing the car to shake at idle.
