2003 Suzuki XL7 • 140,000 miles

My car starts, but does not idle. I can drive it as long as I do not take my foot off the gas. I have done some reading on the subject and understand that I should start by cleaning the IAC valve (or even replace it). Problem is, I do not know where it is located. I have read it is attached to throttle body. I do not know where this is. Any help? Any other ideas on what the problem may be?

The throttle body is the part that is connectd by the air hose of the air cleaner.

The part shold look something like the one in diagram. If you google youtube for IAC, you would get some idea how to go about cleaning the IAC and throttle body.
