on my 1985 300SD?

My 1976 240D used to have a know that adjusted the idle, turn it up when it's cold, turn it down when it's warm.

The reason I ask is that whenever I first start my car, and for the next several miles, I need to drive with two feet. Get's kinda hard when I'm making a right handed turn to prevent the car from stalling.

Any suggestions would be appreciated.
