So I have a V6 accord, and in the pictures there is a hose that when it’s connected there are times where my car wants to turn off like it’s not getting enough air or something, and that little hose sucks in air. When I take it off my car turns on a little better but eats gas like crazy. I need help in finding out what that little hose is connected to or what it is, please help?

I believe that is the vacuum line from the Fuel Pressure Regulator.
