Giant sucking sound!

OK, now that I got your attention....I probably should be able to figure this out by myself, sorry if I'm being lazy. '88 900TC
Symptoms:
Somewhat erratic idle... varies from roughly 800-900RPM, at 3-4 second interval.
When you hit accelerator pedal abruptly (or pull cable quickly) there is a momentary hesitation then pronounced momentary vacuum (sucking) sound. The sound seems to be coming from the throttle body or just below it. So far, I have been unable to find any loose hoses or vacuum leaks using the propane method. Oh, I've also noticed that I don't get boost into the red any more, but that may be unrelated. I don't recall that vacuum sound before but since it seems to be coming from inside the throttle body, maybe it's normal and the idle problem is elsewhere? Thanks for your help.
