I floored it to get out into traffic the other day and then it stalled and quite. It restarted reluctantly and it worked fine for another 100m. After a couple of days of sitting I went to start it and it would only idle and appeared to be missing. When the accelerator was press the engine killed.
I messed with some of the electrical connectors and vacuum lines and the car magically started and ran well. Took it around the block a few time and, again it ran well until I floored it and it killed. Got it running again and just made it into my garage.
Replaced the IACV, which didn't fix the problem. The engine error code flashed 33, the MAP sensor. Replaced the MAP sensor. The car still started but seemed to be missing and killed when the accelerator was pressed.
Replaced the fuel filter, same problem continued. Checked the fuel Pressure at the fuel rail and it was 45#.
No error codes displayed at the present time.
Do you have any ideas of what I should be looking for now?
How many parts do I need to replace before getting lucky??
Thanks,
Dave

how many miles do you have on your car if you have over 100,000 and have never replaced the injectors that could be what the problem is gm used crappy injectors on the 3.1's and the injectors were usually out of spec by 100,000 miles (cleaning wont help) i had the same car and it was having similar problems and it turned out to be the injectors

After repacing the IACV, TPS, MAP, and the fuel filter yield no success. The only error code that I ever got was 33 for the MAP sensor.
Held 45# on the fuel rail and had spark until the engine slowed down and finally quit.
Yes, AAA tow truck to the mechanic. Called them who told me that they took is for a test drive. What is wrong with it?? I said it ran so you could take it for a drive?? GO FIGURE!!
Maybe it didn't like the tow truck.

You say you replaced the MAP did you also replace the vaccum hose and it's tight fit if so trace wires to the computer look for cuts or rubbing they move when you FLOOR IT
