Yeah. Poked my head under the hood this morning, and it looks/sounds like the drive belt tensioner. Anyone know where to get these locally? I'm coming up empty handed via O'Reilly/NAPA.

Also pulled the IAC valve. Looks like it may be bad. Checked between pins 1 and 2 and shows open. Pins 2 and 3, 4 and 5, 5 and 6 are all within spec around 30ohms. Can't seem to find that locally either. At least not in the greater metropolis that is Queen Creek.
