Okay, here's the deal, I just bought this car in early March, and I have to tell a bit of the story of myself and the "progress." I found it in the upper desert (Pearblossom, near Palmdale/Lancaster, SoCal) at an out-of-the-way, largely Mercedes Benz junkyard, where I went with a friend so he could check out and buy a MB Diesel wagon. (he swears by them) There it sat, forlornly knee deep in the weeds and I couldn't resist. The purveyor of the fine assortment of (junk) classics wanted $3K for the car, I had the money, but I finagled it way down because he needed the dough, badly. I aired up the tires and with the help of a crack head forklift driver who "forked" a few dead MB's out of the way, it rolled right out! The dirtiest car (inside) I've ever seen, and/or have ever taken on. This car was NASTY inside when I first saw it.

Idle at 2k is quite high even for the adjustment. Likely there is a vacuum leak somewhere.

Check the AAR valve (see it on the diagram on previous page). It lets air in when the engine is cold to keep the idle up and slowly closes as the engine warms. They are notorious for sticking open. Pull the hose from the air intake plenum and plug with your finger. It should drop the idle to 850 RPM.
