How about the oxygen sensor?
Its a 3 wire type I think, so it should be heated. What if the heating element is broken?

The o2 sensor does not determine fuel trim ratio's untill the car is warm and in closed loop.
I am not familiar with the 3.4DOHC but you could pull the vacuum line off the fuel pressure regulator, turn the key to on, and check for fuel dribbling out.
Have you checked fuel pressure on this one? If it pumps up and drops off, you have a leak somewhere. Probably in, which is why your car keeps idling down but can't.
