Any issues with the car with it being unhooked?

Well the reason I noticed it is because my car has a loud knocking sound and it sounds like a leak from the intake manifold, while checking it out I noticed that.

Check the vacuum lines from the intake and the throttle body/plenum. Could that be a hookup to you o2 sensor on that side?

It looks like an O2 from the research I've done but I checked my O2 sensors and they're all plugged into something already I'll double check

That kinda looks like it would plug into a 02 sensor.
If one of your upstream 02 sensors is unplugged, it won't be long before your Check Engine Light comes on.
