No change as of yet. The SES light remains illuminated and i'm having hesitation issues right at 2k, but only 25%-75% throttle.
I've noticed another strange noise. After cleaning the MAF with CNC I can hear the sound of air, it varies in resonance with RPM and sounds very much like a supercharger.
Vacuum leak? I'm gonna shoot down to autozone and get the codes scanned again tonight.

I've had that sound before, really high pitched right? On mine it just happens every so often, then gone after a day or two. Maybe a small leak in airbox or maf area? Or leaky AIR valves? EGR?
