What are the causes of car shaking during acceleration?
2 Answers
Car shaking during acceleration is caused by: 1. Loose connection between the transmission and chassis; 2. Uneven engagement of the clutch pressure plate and clutch friction disc; 3. Insufficient throttle input or rapid clutch release; 4. Malfunctions in the intake system, ignition system, or fuel system; 5. Clogged fuel injectors. The hazards of car shaking during acceleration include: 1. Damage to the spark plugs, leading to poor ignition; 2. Increased carbon buildup in the fuel injectors; 3. Blockage of the throttle valve and intake passages; 4. Accelerated aging of engine components; 5. Damage to the clutch pressure plate; 6. Increased engine load.
I find the car's acceleration shaking particularly annoying, like last time when I stepped on the gas pedal on my way to work, the car body wobbled, affecting safe driving. Common causes include aging spark plugs. After prolonged use, the electrodes of spark plugs can erode, leading to uneven ignition and causing a cylinder to misfire. Issues with the fuel system are also common, such as clogged fuel injectors or unstable fuel pump pressure, resulting in poor fuel supply. Engine mounting systems, like aging rubber mounts, can amplify vibrations during acceleration. Tire imbalance is more noticeable as shaking at high speeds. I've also encountered carbon buildup on the throttle body and pistons, causing abnormal combustion. It's advisable to first check the spark plugs yourself to see if they need replacement. If the problem persists, it's best to visit a professional shop for a diagnostic scan, as prolonged shaking can damage the engine. Regular maintenance, such as carbon cleaning and suspension checks, can effectively prevent this.
