Need to get those Check Engine Light Codes, that will REALLY help you to solve the rough idle, which sounds like it could be a misfire problem. Does the Check Engine Light ever blink, because that is indicates a severe misfire problem that is ruining your Catalytic Converters, which on a Mercedes is very $$ expensive.
