I'm replacing the EGR valve, IAC valve and Catalytic Converter. I've already located the EGR, but can't seem to find the Idle Air Control Valve to replace it. They, at Autozone, couldn't tell me which I needed so I got both types, but for the life of me can't find where this part is at. Also, I need to know if 2 1/4" in the standard for the inner diameter for my catalytic converter. Any n all help will be appreciated.

iac is to the right of the upper intake manifold underneath the throttle position sensor. 2 1/4 is the standard for the exhaust.
