It's called the IACV or the auxiliary air control (AAC). However, the only way your car should die at idle without it functioning is if you're running your AC. In a manual I'm fairly certain it only comes on when you start the car and when the AC comes on.
I know because I have a manual switch attached to mine, and the engine will even run an electrical fan at an idle speed of about 750 just fine.
It would be a pain to replace; it's back by the firewall (under most of everything else) on the passenger's side. There are some other people online with problems similar to yours, check around in other threads.
