What to Do When a Sedan Shakes While Driving?

[Gary]

Solutions for sedan shaking while driving: 1. Clean engine carbon deposits, as common causes of vehicle shaking include a dirty throttle or severe carbon buildup in the fuel injectors; 2. Replace spark plugs, as faulty spark plugs can also cause the car to shake while driving; 3. Replace fuel pressure system components, as insufficient fuel pump pressure or incorrect readings from the intake pressure sensor can lead to body shaking; 4. Update engine components, as aging engine system parts can also cause car shaking; 5. Perform four-wheel alignment and dynamic balancing, and it is recommended to visit a car 4S shop for four-wheel alignment and dynamic balancing checks.
