This answer was rated:

2000 grandprix 3800 supercharged engine. when you start the engine it idles ood fot 2 to 4 seconds then dies if you rev the engine up and down at 2 to 4 thousand rpm you can keep it running but if you hold a steady throttle or let it idle it dies. It dosent miss or black smoke. Ihave changed the maf sensor and it didnt help. I t acts like a vacum leak but i havent found any and i sprayed starting fluid around the intake and vacum lines and it didnt seem to make a difference.

there are 6 codes....p0102...p0107...p0122...p0128...p1361...p1362

Try another engine computer and recheck the codes. But before you do that, trace all the wires from the MAF and the MAP to the computer. Make sure none are broken. If the wires are ok, then go ahead with the computer. The computer is inside the air cleaner.
