I would definately do the Fuel Pressure Regulator then. From what I understand, it's pretty accessable in those models. I can't really help you as to exactly where it's at, but I'm pretty sure you don't have to take off the manifold. One last thing that I was thinking of: have you checked to see if all of you O2 sensors are screwed in tightly to the exhaust pipe(s)? If not, it can send a bad signal to your computer. Good luck.
