What are the causes of car shaking and bumping?
2 Answers
Car shaking and bumping can be caused by: 1. Poor fuel quality; 2. Carbon buildup on engine valves and intake pipes; 3. Poor lubrication or damage to spark plugs; 4. Insufficient engine power; 5. Aging rubber components in engine mounts and transmission mounts; 6. Aging or leaking high-voltage wires. Solutions for car shaking and bumping: 1. Choose gasoline with guaranteed quality; 2. Clean engine carbon deposits; 3. Apply lubricant to spark plugs; 4. Check for part or mount rubber aging; 5. Inspect the working condition of high-voltage wires and ignition coils; 6. Check for any electrical circuit faults.
As a veteran driver with over 20 years of experience, I've seen too many car vibration issues. The most common is tire-related problems, such as improper tire balancing or wheel rim deformation, especially when you drive above 80 km/h and the steering wheel starts to dance. Then there's misfiring caused by aging spark plugs. Last time my car shook like a massage chair at a red light, but it became quiet immediately after replacing the spark plugs. Another issue is the aging of engine mounts. When these fail, the entire engine vibrates, even making the dashboard tremble. Don't overlook the problem of warped brake discs either; the vibration is particularly noticeable during hard braking. Oh, and with the recent change of seasons, pay attention to tire pressure. A significant difference in pressure between the left and right tires can also cause the car body to sway from side to side.
