Default HELP with a problem

Okay I thought I had a bad injector but I replaced them nd stll have the same problem.

When the car gets warm, and while I'm cruising in VAC it surges and sputters. My A/F Guage read full rich. Eventually I throw a O2 sensor code and drive fine and smooth after that. In boost it is fine. It start this about a week ago but before that it was fine. I haven't tried a new ROM yet.

What could it be? Fuel Pump? O2 sensor, Plugs coil? Any thoughts? It's really annoying. I'm at school throughout the week so my fixing option are limited as I have a very limited amount of tools on hand.

Mods.
14b on DOHC ZC
450cc
TE 2.11 using pm6 codes/Blundars PM7 maps
MSD Blaster SS Coil with MSD Cap
NGK Copper Plugs factory gap (.40 i think)

Any thoughts?

Ya but the car has been street tuned for about 2 weeks on this ROM file running Great and then all of a sudden this came up and has been getting progressively worse.

if it's throwing an O2 code, maybe it is the O2 sensor... do you have a spare one?
