Why does the vehicle shake during acceleration?
1 Answers
Reasons and solutions for car shaking during acceleration: 1. Severe engine carbon deposits. The most common cause is a dirty throttle body or excessive carbon buildup in the fuel injectors. Solution: Clean the fuel system and check if the idle control valve has carbon deposits that need cleaning. 2. Ignition system issues. Check the working condition of spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark plug firing can also cause such symptoms. Solution: Check if the spark plugs have excessive carbon deposits and replace them if necessary. 3. Unstable fuel pressure. Abnormal fuel pump pressure or incorrect readings from the intake pressure sensor can cause vehicle shaking. Solution: Check the fuel pressure and replace components if needed. 4. Aging engine components. Vehicle shaking can also be related to worn engine mounts (also known as engine mounts). Engine mounts are actually the shock absorption system of the engine, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can be transmitted to the steering wheel and cabin, causing shaking at idle. Solution: Replace the components.
