Default Intermittent bucking and rpm drops

I've been having issues with my 01 Millenia 2.5. Occasionally on the highway (60+ mph) the rpms will drop by about 250-500rpm and will lose speed as if I were coasting or the transmission was in neutral. If I press on the gas it will jerk and begin accelerating. Letting off the gas produces the above mentioned coasting/rpm drop. Getting off the highway and onto city streets (35mph) the rpms will bounce up and down and the car will jerk back and forth. I've got no CELs, and have been through all 78 pages pertaining to the Millenia and have found nothing that has helped.
