Applying gas and accelerating in any other circumstance is fine. Car idles fine too and i only feel it in my foot and ass of my seat. Its not like the whole car frame rattles. Depending on your answer I may need to give my service center an earful.

Go to the dealer test drive another V6 thru the same conditions.
