Problem Solved...

Thanks to all who took the time to think and contribute their thoughts to a long saga. And special thanks to Arthur Dalton, Jim F and M. B. Doc ... I can't even imagine what we'd do without you and other gracious contributors.

4Mercedes did correctly rebuild my actuator and tested it (as well as ASR & EC control modules) for 3 days on one of their cars to insure proper operation.

After reinstalling these items my 94 e320, it had a very rough idle and inadequate power. Completely frustrated, I took the car to Star Service Center in Allentown PA. In a short time, Neil realized #4 exhaust valve wasn't operating correctly. He applied some magic and my e320 is running better than ever!!! That's what a good maniac get's paid for... knowledge & skill ...

I probably spent more money "doing it myself" than having Neil doing it all. But the challenge of tearing apart a "MERCEDES BENZ" (much to my family's fear and friends saying "you're crazy") experiencing the friendship and understanding of other MercedesShop listers was well worth the "learning curve." Hopefully I can contribute is some way to "pay back" all of you who have helped and others.

Thanks
Bob

PS Neil 's computer generated an awsome array of codes. "Take it for a ride, hopefully they're all old codes and you've since remiedied their causes." Let's hope so...
