I'm thinking either vacuum leak (like you mentioned) or AAC/IACV. Do you have a FSM for the car? It should help you locate 'em. Make sure they're hooked up properly. They may need cleaning as well.

That's probably your TPS. Not sure where the "idle sensor" is, FSM should help you locate that as well.
I'll try to keep up with this in case you have any more questions.
