I know this post is 16 years old but I didnt want to make a new post. I recently bought an S2k and had this same humming which landed me on this post after doing a google search. Even after reading all the "thats normal" posts I still didn't feel the humming was normal so i did more research. Well to make a long story short, I was able to get the humming noise to go away by adjust the idle screw on the throttle body, in case anyone else wants that humming at idle to go away.
....why?
You took something that's 100% normal and adjusted it to go away, without considering what the adjustment did.
