Hello
I have a 97 GSt and had the same problem!!
I check boost leak, plugs and just about everything else.
It turned out it was the plug wired although the wires seemed to be working they failed under a load
I replaced the wires with NGK ME77 that I purchased from
Ohe’s Performance Parts
Now it pulls thru all gears and no sputter
