Thanks for the replies and the help.

As far as the vacuum leak and idle control valve go; I have the N62 and I can't seem to find anything on any idle control valve. I did actually just start getting some codes as well.

P0300 - Random/Multiple Cylinder Misfire Detected - Confirmed

P0001 - Fuel Volume Regulator Control Circuit/Open - Freeze Frame
P0103 - Mass or Volume Air Flow Circuit High Input - Freeze Frame

This does seem like a vacuum leak or mass air flow sensor malfunction could be my problem. I did just order new crank case vent valves. I'm going to try to get those in this weekend if they are delivered in time...maybe I have a torn diaphragm or something.

Any thoughts?
