is the AIC supposed to buzz?
In diagnostic mode,setting IAC,my IAC will kind of buzz or make an audible sound as it tries to extend the pintle.
It continues to do that untill I unplug it.
I continue to have high idle problems(2000 rpm).
Is IAC toast or what.

The IAC will buzz in diag mode. The motor is being forced to back out and once it is fully backed out the power isnt cut so it just hangs up and makes noise, until you unplug it.
Its like a growl.

I wouldn't consider the sounds mine makes a growl, it's more of a clicking. Sort of intermittent. Is mine toast?
