I have replaced the motor mounts and serpentine belt and my car still vibrates.

Good morning,

The harmonic balancer at the front of the motor and the flywheel at the rear are the components in control for vibrations of the motor.

The balancer is more important as it is a 2 piece unit. When the rubber wears out, the outer ring moves and upsets the balance of the motor.

Just to be sure, are there any codes related to the engine?
