I believe it is normal to get O2 and Air mass codes when you have a vacuum leak.......the computer tries to compensate for the vacuum leak by adjusting the idle electronically.....therefore you get codes......when the real problem is the vacuum hose got knocked off during the water pump install.

I would be real hesitant to agree to a new air intake manifold when the problem is simply they need to just plug the hose back in....

Let me know how it goes.
