Guys I think alot of the rough idle and power issues are ethanol related and wreak havoc with the fuel pumps on bimmers.....I have seen this with my wife's mini cooper s. The key to smooth idle and power is to have the dealer reset the DME to default (basically reset the computer via the OBD 2 port, then i would recommend stabil to clean the fuel system and some injector cleaner following that in the next fill up. Also try to consistently use the same gas station if you have good results with that particular brand fuel. I use Chevron and the issues are gone in my wife's mini which the dealer could not find the issues .
