I hear a humming noise when the car first starts, would that be it, or is it more of an actual buzz?

The car still started rough after my shift last night (sat for 8 hours). Another engineer friend and DeLorean/cars in general buff suggested this could be a symptom of watered-down gas - it sits for a while and the water settles to the bottom of the tank but then gets stirred up when it runs for a little while. I did get my last fillup at a station in the middle of nowhere so it's not outside the realm of possibility. Going to try adding some Heet and see what happens.
