Does a 1987 560SEL have an idle control valve? If so, where is it and what does it look like? The car doesn't run rough or anything, just idles around 1400 when in park and even higher once it warms up. In gear it drops down to abut 850. Several of you have suggested the idle control and that sounds like it might be the solution. But I have no idea what it is or where it is. Help!!! Thanks!!

Let the Buy Parts link be your friend. Left one is the Idle Control Valve and the right one is the Idle Control Unit.

Thanks.. I already changed the idle control valve, thinking that was the problem. Where is the idle control unit and how can I test if it is working (I have a multimeter).
