'97 MERCEDES ENGINE STALLING AT IDLE

1997 Mercedes Benz S420 • V8 2WD Automatic • 201,000 miles

Hey,
I have a 1997 Mercedes S420 that is having a problem when idling or basically at low RPM's. When the engine sits at low rpms and even occasionally just after coming to a stop, the engine simply shuts off. All electronics remain on however power steering is off as well (engine driven I presume). The car will start back up immediately by removing the key and starting normally. Any help would be great!

Bring it in and have the Electronic Accelerator (EA)/ Cruise Control (CC)/ Idle Speed Control (ISC) Actuator (S420) On top center of engine checked and tested-

I just went to an auto shop and had them use a diagnostic device. Results showed a problem with the oxygen sensor, mass air flow sensor, and the secondary air injector system. Does this change what should get checked?
