I agree i am gonna just replace the sensor this week i have narrowed it down to the air/fuel ratio sensor just going bad.

I pray to GOD that they did not put a non fouler on the front air fuel sensor. The sensors in the rear are just regular O2 sensors to measure catalyst efficiency so its ok to do those, but the front sensor is what derives all the air fuel corrections. Replace the sensor and or remove the non fouler if on the front a/f sensor. And what do you mean lessen the amount of stuff getting to the tps?

which left which right..bank one is passenger side correct..
i had some leaks which i fixed and still the light was on..dont remember the number but it was bank one sensor one range/performace
i have non foulers for the rear o2s..i replaced it with a bosch direct fix sensor from discount..let me know please..problems is starting to become a bother lol
