Strange noise after deflood
Can anyone shed some light on the source and cause of this nasty noise?
It cropped up immediately after de-flooding the engine and hasn't left. I've ran the car fairly hard after the deflood, and through 2 complete emissions readiness cycles. No CEL's or pending CEL's, seems to drive fine. SSV has been replaced so I doubt it's that.
The center of the noise seems to be over the ACV next to the air pump, or somewhere in the lower intake manifold... I'm just not sure.
Any opinions?

As an update, the car is throwing P0171 now.
I suppose there's a vac leak somewhere, but I can't find any loose connections or anything obvious. Are there any other common failure points for leaks? Would a failing air pump throw more air into the intake stream?
