Idle Speed....Too high?

[PJayUK]

My W220 seems to idle at around 800-900 RPM, according to some of my research this seems a little on the high side. The car runs perfectly if perhaps a little jerky on the overrun sometimes but otherwise no issues. Its used daily to run to work and back around 70 miles.

Should I worry about this, how do you change the idle speed is it a job of hooking it up to star to sort it?
