The RPM are correct and if they do not flactuate up and down, it seems like you do not have rough idle problem rather have an engine shake at low RPM. If your motor mounts are not bad, check your engine shocks, Front flex disc, Tranny mount, and finally differential mounts. All of these effect the engine shake at idle.

Keep us posted.
Thanks
