Howdy all, I've come into possession of a ruff looking 1984 280 SEL AMG Euro. Tho it runs good, whith the exception of the idle. It's former owner live at a much higher elevation than myself, so the car idles at 1500 RPMs insted of the 600-800 RPMs for a car down here. I tried the idle screw ( brought the idle down just barely lowered it 100 RPMs ). I can't seem to locate the MAP sencor, and the O2 Sencor wire was butchered off, so I can't find the other end. ( I'm prity sure that would fix the problem ). Tho any other advice would be much LIKED.
