I've recently purchased this 16v that is generally in fantastic condition, but for the above issue. Car starts first crank when cold, and runs very strong on the highway or when pressed. However, at times, when warm, the car will struggle to start (I have to give it a lot of gas to start, and then sometimes still stalls), and is also prone to sometimes stalling say when I push in the clutch to coast to a stop light or to downshift for a corner.

I have read as much as I can find here and on other boards, but as this is my first Mercedes, I'm rather lost. I'm reasonably mechanically inclined, and know my way around a multi-meter - I just need some direction.

Thank you!
