What Causes Car Shaking While Driving?
2 Answers
Here are the reasons why a car shakes while driving: 1. Excessive carbon deposits on the fuel injectors and throttle body. During cold starts, these deposits absorb some of the gasoline, leading to a lean air-fuel mixture, difficulty starting, or engine shaking. 2. Issues related to car tires. It is necessary to check the tire pressure, tire wear, and components such as shock absorbers. 3. Shaking caused by abnormalities in the car's fuel supply system or ignition system. Check whether the intake pressure sensor, fuel pressure, and spark plug ignition are normal. 4. Problems with the car's body components. Inspect whether the engine mounts, rubber ball joints, and parts securing the engine are loose, aged, or damaged.
Recently, my car keeps shaking while driving, and this issue is really bothering me. The main cause could be tire problems, such as imbalance or deformation. Last time I had the same issue, getting a wheel balance fixed it. It might also be due to wheel rim deformation or uneven tire pressure, which feels particularly noticeable. Problems with the suspension system, like worn-out shock absorbers or control arm wear, can also cause the car body to shake. I suggest checking the tires and rims first and getting them fixed at a repair shop. If the shaking gets worse at higher speeds, it might be due to an unbalanced driveshaft; if it shakes at low speeds, it could be a brake disc issue. Overall, car shaking affects safe driving, so don’t delay—get it diagnosed and repaired promptly to avoid turning a minor issue into a major one.
