Hello all, I drive a Buick encore 2014 with these codes. P0171 p0137 p2097, not sure if this combo can help pinpoint the exact issue(hoping it’s the same thing for all 3 but am aware it could be all seperate.

I have already changed the o2 sensors, checked and fixed any exhaust leaks and that didn’t fix it.

Not 100% consistant but seems that the wagoner light goes away when outside temps are higher, has been a persistant issue for the past few years and have finally given up and asking for help.

Car performance doesn’t seem to be affected at all so I have been mostly ignoring it and trying to check different things as I have time.

Any help or advice would be greatly appreciated as I have no clue what else to do.
