Problem with Secondary Air Injection System-1995 900S

This system is supposed to only run at startup right? (1995 900S NA)
Here is what I experience:
When I start the car I hear a hissing sound like air being expelled. If I put my hand down on the valve (where the vacuum hose and other hoses meet) by the bottom of the radiator, drivers side, there is TONS of air exiting here. Once the car warms up a little, the valve closes and this air expelling disappears, but I can hear the air pump continuing to run (kinda loud). Isn't this thing supposed to shut off once the engine heats up?
It seems to me that this valve that is expelling air should be closed rather than open at startup and then once it heats up a little, the pump should shut off right???
Any input on things to check (shut off sensor for the pump? Valve actuation?) would be appreciated.
Nick.
