Idle Control Valve
 

My car a 1987 300 E is having some hesitation and rough idle during startup and first 1 minute or so of driving. Researching the site I think the culprit may be the idle contol valve. Since I am a mechanical novice could anybody tell me where to find this part and how to clean it. Thanks.

ist located under the air cleaner....take it off and should be to the front of the engine......heres a picture of it..

Question is, how do you remove it? I think this is the problem with my 85' 380SE. Anywhere here that lists step by step instructions? Thanks.

very simple
 

to remove, just bolted down, be careful not to damage formed hoses (check them for leaks/cracks while you're there. It's right on top of engine front, dead center. Somewhere on this site is discussion about a modification to the ICV hose involving a small jumper that helped out my 380SE - Your 87 may have it (from the factory) Do a search for the mod if you don't have it already.

just stole dima4855's pic from his 81 380sl on a later post. (sorry dima). ICV is dead center in the pic. Attachment 33062

Thanks Derry. Are there any fuel lines running to it, or strictly vacuum lines?
