Should have two 8 or 10mm bolts that hold it down and a gasket. You could start by getting some carb cleaner and trying to clean it out, but it will more than likely be bad.

BTW I don't really know if this is the issue at all. It could be your A/C fan clutch or condensor. I would check it out first. I was only showing you where the IAC was.

I'm gonna try and clean it and see if that does nething shouldn't take too long or cost hardly anything to try.
