unplug IAC and nothing happens
If you unplug the IAC while running what should be the result? When i unplug it, nothing happens, it idles just the same (a little rough). Does this indicate anything or is that normal for the IAC.

Did you unplug the IAC while the car was cold and it was regulating the idle?

IAC does a lot of work when the car is cold / warming up.
What lead you to disconnecting it in the first place?

Also note that the IAC valve will stay in the same position as wherever it was you unplugged it, so I would expect that if you're already warmed up the idle shouldn't change at all when you unplug it.
