Replaced:
MAF
Coils
Injectors (2lbs larger)
Plugs (pre-gapped irridium)
Wires
O2's

Still getting this lean condition.
I have not checked the fuel pressure yet and I am not sure what the LTFT or STFT is supposed to be in %, (that is how my scantool reads it)

But I know that the FP has to be at 44lbs before the car will start so I am assuming that it is ok. If it is a fuel pressure prob, and the FP is fine how would I fix the prob? Adjustable regulator? I can't seem to find one for my beast: 98 GAGT 3.1L

Anyone have any ideas? I do have a scantool so if you have some specs for me to look up I can do that and relate what I find.
