What year V10? Many of them don't even have a downstream (after the cat) O2 sensor.
Sometimes, they register three O2 sensors to some scanners and then refuse to display any readings for that "third" o2 sensor (because it's not really there).
I'd replace the IAC first, right after checking all the vacuum hoses. This sounds very familiar, and is usually the IAC.
