last time I checked mine it was around 850 or so.
I can plug in my scanalyzer when I get home and get a more accurate figure for you if you want.

If you looking for an excuse to spend time on your car then sure, if not, its not a big deal. If you do can you give a very brief description of the vibration you feel at that rpm. I have never noticed mine drop below ~850, even now that its cold out. thanks
