Probable causes of an engine running rich are as follows: 1. Excessive fuel pressure can be cause by restricted fuel return line
2. Defective Oxygen Sensors.
3. Leaking injectors and fuel pressure regulator.
4. Coolant temperature sensor out of calibration.
5. Restricted air intake system.

Since you are only getting the code on one side of the truck I would concentrate on things that only effect that side of the engine and make sure you changed the correct sensor. (Driver's side)
