It's definitely not that. I get that noise all the time, just like you said, when pushing the gas pedal but not pushing hard. Screechy noise. Kind of annoying, but I got used to it.

This noise was different. It was only audible at idle and just over. It was a completely different noise than the SC screechy noise. As far as I know, the screechy SC thing isn't a problem right? Just an annoyance.
