Okay:
This may take a couple test to identify. Because the the drop in performance, check the catalytic converter to make sure it isn't loose inside and ratteling and cauising a power loss. Just tap on the exhaust with a rubber mallot.

If that is good, remove the serp belt and start the engine to see if the sound is gone. NOTE: Only run the engine a few seconds so it doesn't over heat.

If the sound is gone, check each accessory to determine which is causing the noise.

Let me know what you find.
