What Causes Car Vibration While Driving?
2 Answers
The reasons for car vibration while driving are: 1. Excessive carbon deposits on the fuel injector and throttle body. During cold starts, these deposits absorb some of the gasoline, leading to a lean combustible mixture, making starting difficult or causing engine vibration; 2. Issues related to car tires. It is necessary to check the tire pressure, tire wear, shock absorbers, and other components; 3. Vibration caused by abnormalities in the car's fuel supply and ignition systems. Check whether the intake pressure sensor, fuel supply pressure, spark plug firing, etc., are normal; 4. Problems with the car's body components. Check whether the engine mounts, rubber ball joint covers, and parts securing the engine are loose or worn out.
I've been driving for over ten years and often encounter the issue of car shaking while driving. Generally, the most common causes are unbalanced tires or deformed wheel rims. Every time you get new tires, it's essential to perform dynamic balancing immediately; otherwise, the wheels will wobble when rotating at high speeds. Another critical point is problems with the suspension system, such as damaged shock absorbers or aging springs, which become more noticeable when the car bumps and may require part replacement or repair. Never underestimate the braking system; if the brake discs are worn or uneven, the shaking becomes more severe when braking at high speeds. Worn drive shafts or universal joints on the half-shafts can also lead to this condition, especially feeling the car pulling during acceleration. Issues with the engine's ignition system may also cause shaking, such as burnt spark plugs or faulty ignition coils. I recommend regular maintenance checks on these components and addressing any problems immediately to prevent more severe failures and ensure driving safety.
