The car starts, but stalls right away. I can usually play with the throttle, and get the car to rev up. However, in order to rev the car up, I have to play with the throttle alot. If I just mash it, the car stalls. As soon as I let off the throttle, the engine picks up a bit, and runs ok for a second.

Other things I noticed... if I disconnect the MAF sensor, the car idles fine, but I can't give it any throttle. Also, if I disconnect the vacuum hose(big one) off the top of the intake piping, just before the throttle body, it idles fine, but again I can't rev it up.

When I can get the engine to rev up, I can go WOT with it. It doesn't like to hold it, but if I play with the throttle, I can keep the revs up.

Might this be a fuel pressure regulator going bad? And is that what is in the vacuum line that comes off the intake piping I described?

 

Sounds like the classic syptoms of a bad MAF or a huge vac leak.

 

Yea, I was coming to that conclusion upon further investigation. According to the Haynes manual, I was supposed to be getting a reading of around 3.5-5ohms across 2 terminals, and I got a 2.9. Buggers...
