Vacuum leak after changing serp.belt

[97vulcan]

Just as the title says I have a vacuum leak somewhere. It wasnt leaking until I changed my serpentine belt, after that I have a leak. It is slowly bringing my idle down. if I sit for a minute the idle slowly goes lower. When I am driving it, its apparent that there is a leak somewhere. I can hear it wistling when I rev it, but I can't find it. Any suggestions?? Also, I noticed that when I rev the engine, it takes longer for the idle to return to normal.

which belt is it
the one by the intake or the main belt
if it is the one by the intake check over your work you probably knocked a hose loose but it kinda sounds like you egr vacuum hose

Its the serpentine belt, near the coolant tank and such. This is where I think I hear the noise, even when I downshift, I can hear the noise, like a slight wistle, and the RPMs don't seem to drop as fast as before.

Thanks,

To try and find the leak spray some carb cleaner over the various joints/hoses in the engine. If theres a leak you should hear the idle change.
