Need help. Hissing sound on startup....

Hello all.
I need some assistance.
95 Saab 900S 2.3 L Convert. 127K miles
When I start my Saab I heard a hissing sound. On normal startup, my car surges to 1.2-1.3K RPMs for about 15-30 seconds (on a cold start) and then drops down to a normal 1K RPM. During that time I can hear the hissing sound. Sounds just like the valve on a tire being opened. I popped the hood and I can feel air blowing at a pretty good rate from somewhere under the battery. However, I cant pinpoint the source. After about 20-30 seconds, it stops completely.
Car seems to run normal since this started yesterday.
Does anyone have an idea of what is causing this and what the source of the air is?
TIA :)
