Wow, is this just the season for ICV, ICU, and OVP related issues? I think this is the fourth post I've seen for this body type and this sort of problem during the last four days.

I'm seeing the same issue with my '85 380se. I got some great advice on a post I created about a week ago. My deepest fear is that the throttle position switch is broken which'd require me to get under that vacuum and fuel line mess on top to get it out.

Here's a question. Does anyone have the wiring diagram for the W126 ICU going through the OVP and the TPS and the ICV? I think that'd really help me and I'm sure many others to trace down potential trouble spots.

In fact, I think I'll post a thread requesting it.
