the imrc module is rattling. it has a rough idle at start up. i had the ids hooked uped to it at ford ant took it for a drive. the only issue that was found was the imrc voltage stays at 0.6 volts and does not change no matter where the rpms are at. Does this mean the imrc is bad?

Probably bad. In my experience, when you hear the rattling noise after startup, it is due to the plastic pully in the imrc control being stripped out. There are several how-to's that explain removal and opening of the imrc to inspect it. In your case, the thing to look for after opening the imrc is plastic shavings. That would mean the imrc motor shaft is just spinning inside the pulley, but the pulley is not turning and pulling on the imrc cable.
