What Causes Body Shaking When Starting and Turning?
3 Answers
There are two main reasons: 1. Damaged spark plugs: Wear on the spark plug electrode gap leads to insufficient spark, causing incomplete combustion of the air-fuel mixture and resulting in shaking during acceleration. Additionally, cracks in the ceramic part of the spark plug can prevent it from firing, leading to one cylinder not working and causing acceleration shake. 2. Poor fuel quality: This results in poor atomization from the fuel injectors, leading to incomplete combustion of the air-fuel mixture in the cylinder and causing idle shake. It is recommended to use higher-grade gasoline after finishing the current tank and to perform a fuel system cleaning.
I've been driving for over twenty years and have encountered body shaking during starts and turns many times, usually due to issues with the steering system. Worn steering rods or damaged drive shafts can cause uneven force distribution during turns, making the body sway. Tires are also a problem—insufficient pressure or severe wear reduces grip, leading to pronounced shaking during start-turn combinations. Faults in the engine ignition system, such as spark plugs or coils, along with unstable idling, can amplify the shaking. Loose chassis components or failed shock absorbers shouldn't be ignored either, as they intensify the shaking sensation when turning under stress. Safety first—I recommend getting a comprehensive check at a professional repair shop as soon as you notice it, rather than waiting for an accident to regret it. Regular maintenance of the steering system and tires can prevent such failures.
As a parent who frequently drives my kids around, I feel noticeable body shaking when turning or starting my family car, which is quite alarming. A friend pointed out that it's likely a tire issue, such as low pressure or worn treads, affecting turning stability. Loose steering linkage could also cause force imbalance, making the shaking more pronounced. For safety, I make it a habit to check tire pressure monthly, ensuring it's inflated to the standard value. If the shaking persists, I don't risk driving further but head straight to the repair shop. After all, safety is paramount for family cars—addressing minor issues early prevents potential accident risks.
