I have the same thing, at a slightly lower rpm. Mine is most noticeable at about 1900 to 2000. I feel it best with door open a foot and hand at rear of door top. I had noticed that my crank pulley was wobbling just a tiny bit (maybe 1/2 mm at front edge) and after reading a lot of posts about these pulleys coming apart at the rubber damper interface, I changed it to a solid aluminum underdrive, and about 30% of the vibration is gone. My guess is that these engines may have a bit of resonance at that rpm that can't be damped out, and 11 year old engine mounts let it thru so you can feel it.
The underdrive pulley seems fine so far, voltmeter shows 14.2 at 600 rpm idle, no load, 13.7 with low beams on, and 12.85 and slowly falling with fogs, radio and A/C on. So as long as long periods of high demand at idle are avoided, the battery will be OK.
