Question 1997 S420 idles rough when I turn A/C on. Please Help

Hello to all,
I Live in L.V. where there are very hot temperatures. When I turn on the ac and come to a stop or red light the car idles rough and feels like it is going to stall. This just started this year. Can any one suggest anything to help me get to the bottom of this annoying problem. Thank you and have a great week!

Try posting this on the W140 S-Class forum, found in the sedans section. And please provide them with some of the service history. Good luck and welcome to BW.
