The IAC or Idle air control valve does not have vacuum hoses connected to it. It is electric and bolted directly to the throttle body. So if you go like Napa online and put in part number 339657 you will see a picture of it. If you think it is plugged you will need to go to your local parts store and get a gasket for it first then remove it and clean it. What is the problems you are having?
