anyone have any knowledge or links on how the clean out oxygen or exhaust sensors. I think this might be the reason for my poor FE these days.

I have no check engine light but a P0420 (I think) code has come up in the past and was cancelled again about a year ago. however recently car slightly jerks under acceleration and FE should be better than what it is. don't want to get a new sensor just yet for incise it might be something else.

I have an obd2 plug and torque app but im not sure what the graphs are telling me and what they should be telling me
