08 Ford F-150 135k miles.

Has had had check engine light on for couple years with p0420.

Truck ran fine for most part. Maybe a little sluggish with power but good nonetheless.

At at one point I replace all 4 o2 sensors and code remained.

In last 6 mos the truck has been stalling and misfiring intermittently.

I cut out Bank 1 cat converter and installed new magnaflow converter. And changed fuel filter which was horribly full of gunk. P0420 went away. Then got p2195 and p2197.

Today i I cut out bank 2 cat converter and installed magnaflow converter. P2195 went away but p2197 remains.

I bought the fixd odb scanner abdceas able able to pull the below data with running at idle.

I have a new o2 sensorcarriving tomorrow I am planning on replacing bank 2 upstream sensor with. Any suggestions what else I may be missing? The truck starts and fires great. Just very sluggish on power and will hesitate and misfire at times.

The -100% lt fuel trim Doesn't tell you anything? I'd imagine this data is invaluable to those that know engines.
