Car running loud in park?

I have a 2003 Pontiac Vibe(I know, first mistake), and for the past few days it's been quite loud in park, but sounds normal in any other gear. The catalytic converter needs replaced (according to an OBDII code), but the sound is coming from under the hood. It sounds like the engine is revving, but the TPS doesn't move. Does anyone have any insight?

Could be one of the belts. Sometimes it can make it seem like its your engine.
