Why does the car shake when running?

[LilyFitz]

The reasons why the car shakes when running are: 1. Excessive carbon deposits on the fuel injector and throttle valve; 2. Faults caused by car tires; 3. Abnormalities in the car's fuel supply system and ignition system; 4. Incorrect readings or poor performance of the intake pressure sensor; 5. Aging of engine components; 6. Abnormal fuel supply pressure from the car's fuel pump. The solutions to the car shaking when running are: 1. Clean the fuel system, check if the idle speed motor has carbon deposits, and clean it in time; 2. Check the tire pressure, tire wear, shock absorbers, and other components; 3. Check whether the intake pressure sensor, fuel supply pressure, and spark plug firing are normal; 4. Check if the engine mounts, rubber ball joints, and components fixing the engine are loose or aged and damaged.
