Lol, you added to many zero's there buddy because if your car idles at 7000+ RPM that would be crazy loud and your car would be out of gas in no time.

To the OP, mines never went below 600 RPM and I have a 328i. But just make sure your new spark plugs are tightened/torqued properly and see if there is any difference. Also about the vibration try to see if your motor mounts are leaking any fluids.
