AIC sounds like a vacuum leak

1988 16V, non-turbo, 5spd.
When I changed the oil and filter yesterday, I noticed the sound of a vacuum leak at the AIC. The noise sounds like it is coming from the AIC hose (part#7587173 on the saab site). When i wrap my hand around this hose, the noise sounds like it either stops or is muffled. I pulled the hose, looked it over and can't find any cracks or holes in it. It seems to fit snugly on both the AIC and the throttle body. All of the small vacuum lines at the T near the oil filter are hooked up properly. I will add that my warm idle can fluctuate up and down at times.
Does anybody have any thoughts or suggestions on this? Thanks ahead of time for your help and input!!!
