				Cel P0410 P1411 secondary air
			 
 
			I got these 2 codes after I change my AOS and cleaned out the air intake. I know these codes mean I probably have a vacuum leak. I can actually hear some hissing so I started checking all the hose and I found that this line leaks when I move it a little. Can anyone tell me what this is exactly and how hard is it to replace. It's the hose circled in red.

			Check out Jager's thread on cleaning the exhaust ports above the main cats.
 (No, not THOSE cats......)

 That hose supplys vacuum to the power brake booster.  The connecter at the intake manifold has a nylon "C" shaped shim to lock it in place, make sure it is doing it's job. There is also a small  O-ring seal at the connection secured to the intake by 2 screws.
 
 Your codes indicate your SAI is not effective, so if you hear the pump operating after a cold start it is not effectively leaning the AFR seen by the secondary O2 sensors.   
Check the link posted by Timco.

			Jager's post on cleaning the exhaust cats was posted for code P0410. I am getting both codes  and I can hear vacuum leaking from that hose. Could a leak from that hose cause those codes?

 I don't see how they could be related, but obviously you don't want a vacuum leak to your brake booster so I would be fixing that 1st.

			If there is a leak on your brake booster vacuum line, you will feel the braking poor compared to normal....

			The leak happens when I move the hose a little. I think that the leak is very minor until you twist the hose a little. I haven't really noticed any difference in braking but I halso haven't driven it all that much since last summer. Just wondering if this leak would trigger the cel codes.

I had a leak on that hose, but the braking wasn't affected. I think there's a check valve along the way that doesn't allow the brake booster to lose vacuum.
 
I tried driving the car with the hose disconnected while troubleshooting, and it took a tremendous amount of force to push that pedal down, almost impossible to stop the car without that vacuum line. Never thought it would have such an impact.

			Did that leak give you any codes?

Yes, P1128 and P1130, oxygen adaptation rich threshold in both banks.
