IAC sounds like a horn!

[Little Red]

Had starting issues when cold and after searching on this fine site I bought a used IAC. It starts better now when cold, always like new when warm but the IAC sounds like a stupid horn at idle. It don't hurt nothing but I get strange looks from other people when I sit next to them at a light. They think my horn is stuck LOL!!!!!!! I know it's the IAC because I unplugged it and the horn noise quit. You can also feel it vibrate. ( My GF would love it). Can you spray some stuff in it to shut it up?
