What Causes Body Vibration When Accelerating Hard?

[AbigailAnn]

Reasons for body vibration when accelerating hard include damaged spark plugs, poor fuel quality, bent half-shafts, etc. Below are detailed explanations about body vibration during hard acceleration: Damaged spark plugs: Worn spark plug gaps result in insufficient ignition, causing incomplete combustion of the air-fuel mixture and vibration during acceleration. Cracks in the ceramic part of spark plugs may prevent ignition entirely. Poor fuel quality: Low-quality fuel leads to poor atomization by fuel injectors, resulting in incomplete combustion of the mixture in the cylinders. Bent half-shafts: Issues like bent vehicle half-shafts can cause rhythmic vibration in the front of the car.
