Aos = pita

[steveng1993]

Just swapped out mine this afternoon on my 2001 2.7.
What I learned getting it on and off.
Move oil pipe out of the way.
move 2 big things of wires out of the way.
Unbolt o2 sensor wire holder that is next to the lowest hose.
Use small screw drives to pry the sides of the lower quick connect hose open unless you have monster hands.
I bought a new clamp for the lower hose, it came with a little blue clip that held it open while you are putting it back together. When you pull the clip off after getting it on pull it straight off from the top side of the engine. I wasn't sure how to unclip it and I tried from the bottom and pulling it down which caused the hose and clip to unseat.
