I would suggest that you take your IC off and look. There are 4 vacuum lines that connect to the UIM as well as the brake booster line all in that area.

If it's on the passengers side, check the airpump hoses. It makes a hissing sound above 3800rpms normally when dumping air to the atmosphere instead of the catalytic converter. If you hear it at idle or lower RPMS, one of the 3 hoses may have popped off.
