AHHHH it's a vent! Well I guess I got worked up for nothing 
Not Sure What This Is???
Not Sure What This Is??? I was doing the throttle body bypass since I have everything apart and noticed this hanging around with nothing connected to it. There is not a hose in sight to plug into it either. Anyone know what this is? Do I need to hook it back up somewhere?

Too close up for me to tell based on location. It's obviously a vacuum solenoid, but not sure which one. I think there's 2-3. One for the EGR, which is on the driver side of the intake towards the back, one on the pass side of the intake about mid-motor and I think possibly another for the heater coolant control valve.

Uh, well kinda. It's not meant to be atmospherically vented lol It's supposed to go, probably, to the EVAP canister. I'd assume the connected side goes into the intake? If so, and that solenoid opens, that's a vacuum leak.

One goes to the throttle body and the one that is unhooked on yours usually goes to a hard line that goes under the front of the intake and hooks to the evap cannister hard line in the fuel line loom.
