Are you talking about one of the CCV hoses? I am dealing with something similar - rough idle, and codes P0171 and P0174 (left and right banks running lean) and the SES light on along with the 'Increased Emissions' message. Seems like I have a vaccuum leak because when I spray carb-cleaner on the side of the intake manifold - the rpm surges a bit. Haven't seen exactly where the leak is though.

Ordered the CCV kit, but dreading the DIY on it since I've heard its not fun. Any input from you is greatly appreciated. Also, does the DISA look pretty bent out of shape? I took mine out, but it looked fine and held the flap open when I covered the vaccuum hole with my finger. 74k miles on my M54.
