still acting up under part throttle when not warmed up
when the truck is not warmed up, it will spit and sputter and jerk you all around. i cleaned the o2s with a torch "allen nelson told me to along with members on here" and it acted right for about 20 mins then started doing this all again. i have a code but need to have it read.

I Think it's only while your in open loop that your having a problem, Mine does the same thing till it gets warmed up. I can give it gas in neutral and it'll sputter while accelerating, but once warmed up it's just fine

I recommend NGK brand sensors. Mine was doing the same thing (spudder would go away when throttle was pressed about 75%, but would throw me back in the seat!) and when I went to the NGK's it hasn't done it since. Seems to be a sideeffect of no cats and/or longtube headers from what I can tell. The stock front O2's just crap out after a while, probably because they don't heat up as fast without the cats. The vette O2's are supposed to be better as well, but I haven't tried them.
