Anyone willing to test their IAC valve for me?

I am having some idle problems, I suspect it is the IAC. I think that the valve is not opening all the way so I get a bad idle and no codes from the ecu because the valve still functions. I ned to know how much the valve opens when connected to battery voltage. Mine is opening a little, and it clicks, but I dont know if it is supposed to open more than this or not. Cmon, someone please help me out.
