How’s it going fellas, I’d appreciate some help if anyone else has ran into this.

So I recently hooked up a scanner on my 07 v6 4.0 and it threw me a few codes with all retaining to O2 sensor faults. What seems weird to me is how it’s saying both sensors are reading both rich and lean. I would say the car is definitely running rich. I can easily smell the exhaust. While driving sometimes it’ll do well but most often it’ll be super hesitant after shifting gears. As in I can floor the gas pedal and it barely start climbing. So far I’ve replaced the TPS sensor, The MAF sensor and all the plugs and wires. I’ll type out the codes here:P2197
02 Sensor Signal Biased/Stuck,Lean - Bank 2, Sensor 1,DTC Severity 2 of 3

P2198
02 Sensor Signal Biased/Stuck,Rich = Bank 2. Sensor 1

P2196
02 Sensor Signal Biased/Stuck,Rich = Bank 1, Sensor 1

P2195
02 Sensor Signal Biased/Stuck,Lean- Bank 1, Sensor 1

Any help would be mostly appreciated.
