Air fuel ratio

Air fuel ratio
I have a 2002 is300 catless headers with k and n intake/filter, and throttle lock. i can’t seem to get running perfect. I had a code for bank 1 sensor 2. It’s been replaced before but I replaced it again and it is reading on my scanner. My upstream o2 sensors are reading ok but not great, jumping around a lot. however downstream is reading 0v and 0.1v. From what I understand that should affect fuel trim correct? My short fuel trim is about 7-14% for both bank one and two. Any thoughts and what might cause high fuel trim?
