On my '89 420SEL the stalling and severe bog on throttle application was caused by a failing ignition coil. You might test your spark through a spare spark plug. Mine wouldn't fire with an adequate arc. It solved all my problems after I finally got the right one to replace it. The catalogs at the parts places are wrong. Do a search, we already talked about the right Bosch number.
