It might not be just one thing.
In addition to turbocon86's suggestion, check the hose between the bypass valve and the intake manifold for cracks. They get brittle after a couple of decades of underhood heat and oil. With the effort of working on the bypass valve, they can crack enough to become a major vacuum leak. (BTDT - replaced the one on my '89 SPG a few months ago for just that reason.)
You didn't mention this: make sure that the electrical connector and the hoses on the AIC valve are secure.
