defective IACV?

I just ruined my IAC cleaning with TB spray and it didn't even need it. Baking @250F for an hour brought it back to life slightly but only as a handicap. Re-oiling didn't do anything. With 12V hooked up it would just jerk a little and while installed, would stall the Engine. "Autopsy" didn't bring any explanations. I would not recommend flooding it with cleaner and then letting it sit. Instead, hold the unit...

My daughter's cougar makes a whoop-whoop-whoop noise occasionally which kind of sounds like an anti-lock module cycling or a CV joint. However, it's coming out of the intake as you can hear it real clear when the filter's off. It doesn't do it all the time, but normally right after letting off the throttle at slower speeds, and just before the secondaries close on engine wind down.
