1995 E300 Idle fluctuating

Sorry guys,E300D!

What regulates/controls the engine idle speed?
Engine used to idle at 600 rpm if the transmission is in park or in gear with brake depressed. Now if it is in park it idles at 700rpm and drops down to 400rpm when in gear with brake depressed!

Thanks for any help.
Rick
