The idle air has four wires going to it on a square shaped plug. Sounds like you pulled your emissions breather return line off, or your main vacuum that runs over to the purge, etc.

The Idle Air is just below the TPS on the passenger side of the engine. It is an electric motor that controls idle air volume.
