I will go through these ideas and see how dirty things are, clean them, and replace them if I need to. I didn't see though the location of the IAC or PCV. Are they easily accessible from the engine bay? I'm googled for images, but it didn't show me locations.
PCV is right under plastic engine cover, driver's side, front. See that square part sticking out, it's right under that.
