When I mash the Throttle on my 94 E500 the engine will sometimes stumble once or twice before I back off the throttle. In a search of the posts I saw reference to either a fuel accumulator problem or an electrical problem. How do I check for these problems or is it best left to my dealer?

This is best left to the dealer. Many independent techs even have a hard time witht the EA (electronic accelerator) because of how complex it all is. Many times you will see problems like this that can be caused by faulty distributor caps though. You can remove them with a 5mm allen and inspect. Any green stuff and they are gone.
