Default ? about 02's

I have been adjusting my pe table. I can't get the 02 voltages to come down. I had about .960 to start with. They are pretty consistent through an entire wot run. I leaned the table all the way to the point it's pinging, and still the voltages haven't changed much. Maybe .945. I can't get them anywhere near .890. Could my 02's be wore out? I don't have any dtc's, but I have noticed the engine running rough after making a full throtle run. After a couple minutes it smoothes back out. I think the 02's are original, and the car has about 56k on it. I had to splice some extra wire on them when I put my lt's on, but since I don't have any dtc's, I figured they were ok. Should I just get a new set and try them?

This should probably be in the PCM/Tuning section.

you need a WB to properly tune WOT

NB's are not accurate for anything other than stoich

Thanks, but I knew that. Even if the 02's aren't acurate enough, the voltage should still drop when you pull fuel, and mine don't.
