Has any one had this issue? I have a 2013 825i with about 400 hours, and at start up in the morning it starts right up but the idle really fluctuates quite a bit until after about 2-4 minutes of idling. It almost get low enough on that it sounds like its going to die, but it has not yet. It just seems to be getting worse? Possible bad gas? I only run 91, with no ethanol according to the pump at Fleet farm.
