If you can separate "RPM dependent" from "Vehicle speed dependent" from "Load dependent" then it creates a whole long list of things you don't have to worry about.

It's definitely rpm dependent, but load effects the severity. In park you can feel the vibration grow between 2800-3000 rpm and it's at its worst from 3000-3500rpm. It is still there, but subsides after 3500 rpm.

While driving the car, the vibration is worse during moderate acceleration. At full throttle the vibration is present but not as severe.

Motor mounts perhaps? Those have been in the car since I purchased it in 98.
