What Causes Car Vibration at High Speeds?
1 Answers
Reasons for car vibration at high speeds: 1. Ignition system failure: Issues with spark plugs, high-voltage wires, or ignition coils can lead to poor ignition system performance, triggering the engine warning light accompanied by vibration. 2. Overly rich air-fuel mixture in the cylinders: This may cause knocking and vibration. 3. Abnormal fuel supply pressure: This can also result in car vibration. 4. Faulty idle control valve or wiring. If the engine warning light flashes and the car shakes, it is recommended to stop immediately for safety, avoid continuing to drive, and call a 4S shop or professional auto repair shop for assistance, requesting a tow truck or waiting for rescue.
