It sounds as if you have a vacuum leak. It could be at the hose for the power brakes, pcv valve or the EGR Valve hose leaking. You may also have a bad fuel pressure regulator. Let me know if I can be of further assistance.

Withoutknowing if the check engine light is on it could be a variety of things including but not limited to the o2 sensor, throttle positioning sensor, and the MAF and MAP sensors. Best diagnosed by using an OBDII scanner to scan for codes. If no codes are present I would then check for the pressure coming from the fuel pump to make sure it is still functioning.

Might be the IAC...a good way to test this is while idling if possible, turn on the rear defroster. The rpm's should pick up. If the engine stalls at this point or the rpm's don't increase...replace it.
