Hello, if a car is vibrating at idle only, but has normal power with no driveability issues or check engine light on, the most likely failure is collapsed motor mounts. Motor mounts are rubber insulators that are attached between the motor and frame. Their purpose is to isolate the engine vibration from the chassis of the vehicle. When motor mounts collapse or break, the vibrations from the engine will be transmitted through the chassis.
