Why Does the Car Shake More and More Severely?

[OMaria]

Reasons for severe car shaking are as follows: 1. Ignition system issues: If there is a malfunction in the car's ignition system, it can lead to poor ignition system performance, suboptimal spark plug firing, and other problems, resulting in unstable idling. 2. Engine mount deterioration or loosening: Engine mounts are rubber blocks placed between the engine and the car frame. 3. Carbon buildup problems: Carbon deposits include cylinder carbon buildup, throttle body carbon buildup, spark plug carbon buildup, and intake carbon buildup. When there is excessive carbon buildup inside the engine, the car's ignition energy, intake efficiency, and air-fuel mixture ratio are affected, leading to unstable power output and shaking during idling and acceleration.
