I was having forced idle and stuck open error codes, so replaced throttle body assembly and those ceased. Now looking at my log data, my bank 1 o2 looks like it may be lazy. Haven't gotten any o2 codes so far but bank 1 definitely sits more in the middle voltage range than bank 2, however both sensors sometimes seem slow to respond at all and my fuel trims I think correspond to that as well.

Truck is a 5.4 3v 2004 f150. All stock except k&n CAI and cat & muffler delete. Only mods on the tune are rear o2's turned off and COT disabled.
If someone who has more knowledge about these readings can suggest something? I don't know too much as far as these specifics go. I am looking to keep my truck's ECM basically the same as from the factory besides tuning for the cat delete which has been done already.
