    Even while you foot is off the brakes? Mine is not so much a vibration as a bounce. We have another car that I bought that was still for four years. My Monte Carlo has almost the same frequency of oscillation as the car with 4 year flat spotted tires.

    Just wondering if the bounce in the seat is from the motor moving around too much. Will know more tonight I guess.

    OK, motor mounts changed to solid rubber mounts. I flipped the radiator support mounts also. I can tell a difference in the vehicle dynamics but the original problem I am chasing is still there.

    Now what next? Is it the 25 lbs of road force bouncing the car around?
