What Causes Car Shaking When Accelerating?
2 Answers
Car shaking when accelerating 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 when accelerating include: 1. Damage to the car's spark plugs, leading to poor ignition; 2. Increased carbon buildup in the fuel injectors; 3. Blockage of the throttle body and intake passages; 4. Accelerated aging of engine components; 5. Damage to the clutch pressure plate; 6. Increased engine load.
I've encountered this situation before, usually caused by carbon buildup in the engine. Especially when there's severe carbon deposits in the throttle body and fuel injectors, the engine struggles to breathe when you press the accelerator, making the car shake noticeably. Worn spark plugs are another common cause - unstable ignition can make acceleration feel jerky. If the shaking occurs right after refueling, it might be due to poor fuel quality or water in the fuel tank. While less common, tire deformation or wheel imbalance can indeed make the steering wheel shake during hard acceleration. It's best to clean the throttle body promptly and check the spark plugs' condition, avoiding prolonged low-speed driving that accumulates carbon deposits. These issues actually relate to daily driving safety, so don't wait until they become serious to address them.
