Am I right on this diag?
Im in MN, so its been around 10-20 degrees at most recently. My car will start fine after sitting for hours. But sometimes it'll kill during idle after 5-10mins, or will die while sitting at a stop light or sign. It doesn't stutter at all, it just shuts off. When I try to start it back up, it just cranks, and never fires up. I'll let it sit for a few (5-10, sometimes more) minutes, then itll start back up.
From what i've gathered from researching, is that its my Crankshaft position sensor. Local MB dealer sells it for 150.00 w/tax, and has it in stock. I want to fix it tonight if possible. Is this my best route, just replace the damn thing? Its really embarrassing to sit at a stop light with your hazards on, in a damn luxury car.
Lemme know your thoughts

Oh, research Mass Air Sensor or Air Mass Sensor (same part) too. This is another problematic part. Symptom is rough idling. Actually, this problem will 'show' with a diag w/computer. It will read 'Fuel Trim Malfunction'.
Just get used to coming on this (and other) forums to get more information before making costly repairs.
