Q: Car vibrating while in drive or idling

Hi, it sounds like your motor mounts have worn out or are beginning to wear out. Motor mounts connect the engine to the frame of the body and help absorb the vibrations that the engine create, to make the ride smooth and enjoyable. They are made out of different types of rubber and over time they can dry out and begin cracking. If the engine isn’t secured properly, it will move around while you are driving which can damage the engine and other components underneath the hood. You should have a technician inspect the source of the vibrations and ensure the mounts are still in good shape.
