Not in less than 25 words, but for your reading pleasure - here you go...There is no "idle screw" on your model mercedes. It is a fuel injected (in other words, not an older normal aspirator type carbuertor), computer controlled idle/air mixture. There is an idle/air speed control valve part (see picture ) that connects to the idle/air control unit (another programmable computer - one of about 20 in this model) that determines idle speed and air/fuel mixture. Mercedes is top of the line, but really too complicated for the average joe to work on. Best to pay the man and take to a mercedes specialist shop.Idle screw location, 1982 mercedes benz 380sec - 493db71d-2619-442c-8065-798539caa300.jpg

    You are most welcome. Hope you get it fixed without costing an arm & a leg, but it being a Mercedes, I doubt it. Great cars engineered by masters, but they are VERY proud of their work and charge accordingly.

check your main harness wire. The harness wire becomes brittle and will eventually short circuit your car. Stalling and hard starting is the initial symptom. If not replaced soon, your car will smoke and eventually affect your computer box
