ok when ever i enter PE at wot the car breaks up and bucks violent it does this in 1 thru 6 but only at wot. my driver side 02 reads 160mv, and the passenger side 02 reads 972mv during wot and i do have ses codes p0134 and couple others saying that theres insuffeint acitvity on the driver side 02 and insuffeint switching and that the driver side bank is to lean during nomral operation as i left the afr 14.7 over all. it has a comanded 12.7 in pe with stock timing. the car it self is just a full exhaust car. the 02's are bosch for 02 c5 as u need for long tube cars. but there only a few months old, are they shot or is it something else?

 

One 02 reads lean and the other rich. I would replace both or at least check the wiring on them. Or you could also have a fuel/mechanical problem that is causing the one bank to run lean.

 

Also, can you confirm that you are going into open loop (FTC 15 or 22) at WOT?
