The only thing that sounds like a vacuum on that car would be the Secondary Air Pump. If thats happening either the Pump Relay is stuck, trigger wire from the PCM to the relay is shorted or the PCM is internally shorted. Really hard to diagnose over the net. Best thing to do is take it to a compenant repair shop and have it diagnosed properly. Electrical issues can really get tricky and tie up lots of tme and cash.

Good Luck.
