There is a tube i need to replace right next to EGR assenbely help identify plz

What is your question?

Right below the EGR assembly There us two black hoses i think they have to do with air because its feels like its sucking my finger in through a small hole. I'm getting a random missfire code and a 02 Lean stuck bank1 sensor 1 and 02 lean stuck bank 1 sensor 2 code The description of the house it curves into a L where it plugs into the truck next to the EGR assembly then it goes down maybe a foot or 2 and it curves into another L next to the sparkplug coil pack cover and its held down by a bolt or two and has a harness plugged into it. I just need the name of that tube so i can replace it. and get rid of the rough idle just incase a extra way to find all of this its in the middle back of the engine next to the manifold upper accessory bracket kinda but all the way in the back

What makes this problem better or worse?

The misfire starts once engine high rev start stops

How long has your 2004 Lincoln Aviator had this problem?

Not very long ive replaced all spark plugs and spark wires
