occasionally at idle i get this howling from around my TB.... i thought maybe it was my new serpantine cause i replaced one serpantine and then it immediatly got chewed up because of a loose tensioner but we tightened the tensioner, replaced the belt again, and as far as i can tell the belt isnt rubbing, but i sometimes get this howl, and i notice that my boost gauge goes from around 20 vac to like 22 vac during the howl.... maybe a vac leak of some kind?

i had that problem on my 89 along with a high idle, and it was my IAC. replaced it and everything was o.k. after that.
 
Well yes...and no

You can try to clean it but chances are that you'll end up needing a new one. Ask at the local ford dealers (don't bother with a non Ford part) and if they can't beat $60 get ahold of Dan Newman at Five Star Ford in Scottsdale AZ.
