I have a code for P0161. I have changed the 02 sensor once and it didn't fix the code anyone know what it might be. Or can I get a programmer with a custom tune to override the 02 Sensors

Code P0161 indicates that the problem is the circuit and not the sensor. Check the wiring and connectors for corrosion and/or broken/pinched wires.
