What Causes Car Shaking When Accelerating?
2 Answers
Car shaking when accelerating can be caused by not releasing the handbrake, insufficient engine oil, abnormal spark plugs, or tire issues. The specific reasons are as follows: Not releasing the handbrake: If the handbrake is not released, the vehicle may shake intermittently while driving because the parking brake constantly rubs against the tires, causing the vehicle to shake. Insufficient engine oil: If the vehicle lacks engine oil, has insufficient oil supply, or the oil quality is poor, it can make the engine work harder, leading to vehicle shaking. It is important to regularly check the oil level and cleanliness. Abnormal spark plugs: If the spark plugs are burnt, have excessive gaps, or are loose, the vehicle may shake. In such cases, stop the vehicle and carefully inspect the spark plugs for integrity. If you have the tools, remove the spark plugs for inspection. Visit a repair shop promptly for maintenance. Tire issues: Sometimes, insufficient tire pressure or imbalance can cause the vehicle to shake. Carefully check the tire pressure and look for any abnormal wear. If there is wear, it indicates tire imbalance, and you should visit a repair shop for inspection and repair.
Having driven for decades, I've encountered many issues with engine shaking, especially when accelerating—the car would wobble like it's dancing. This is usually due to aging spark plugs with excessive carbon buildup, causing misfires. I remember one time after refueling, the shaking was so severe that upon inspection, the spark plugs were found to be burnt out. Replacing them immediately stabilized the car. Fuel system problems are also common, such as insufficient fuel pump pressure or clogged injectors leading to uneven fuel supply. The intake system shouldn't be overlooked either; a dirty air filter can restrict airflow, making the engine struggle for breath. Unbalanced tires or worn suspension components can also cause shaking—it's best to get a comprehensive check at a professional shop. Don't slack on regular maintenance; replacing spark plugs every 20,000 kilometers can prevent future troubles. Ignoring this issue for too long not only damages the car but also increases fuel consumption—definitely not worth it.
