What Are the Causes of Vehicle Body Shaking During Acceleration?
2 Answers
Vehicle body shaking during acceleration is caused by: 1. Dirty throttle body; 2. Excessive carbon buildup in the fuel injectors; 3. Excessive carbon buildup in the intake manifold; 4. Engine malfunction; 5. Insufficient cylinder pressure; 6. Faulty drive shaft; 7. Malfunction in the fuel system; 8. Aging engine components; 9. Ignition system failure. Solutions for car acceleration shaking include: 1. Replacing filters: including oil filter, fuel filter, and air filter, which can improve filtration efficiency, reduce impurities, and ensure more complete engine combustion; 2. Cleaning carbon deposits: including spark plug carbon deposits, throttle body carbon deposits, and cylinder carbon deposits.
As a veteran driver with twenty years of experience, I've encountered many cases of car body shaking during acceleration. The most common causes are unbalanced tires or uneven wear, where eccentric wheels cause vibrations when rotating. Issues in the drivetrain, such as a damaged driveshaft or worn universal joints, can also make the car shake when speeding up. On the engine side, aging spark plugs or faulty ignition coils lead to uneven combustion, making the shaking more noticeable. Suspension components like failed shock absorbers may also cause vibrations. I recommend first checking tire pressure and wear condition. If the shaking persists after balancing, a professional shop should conduct a comprehensive diagnosis of the drivetrain and engine. Don't delay, as prolonged driving in this condition can cause significant vehicle damage and potential safety hazards. Regular maintenance of tires and the ignition system can prevent such issues, saving you trouble on the road.
