E13: right bank O2 sensor, no data
F48: low refrigerant level in A/C system
Neither of these is likely to cause rough idle, but I would change the sensor.
If that cure it, great.
If not, make sure the vacuum hose on the fuel pressure regulator (at end of fuel rail) is tight at both ends and not cracked or leaking. Then pull the vacuum hose off the regulator and see if there is any fuel in the vacuum hose. If yes, replace regulator.
I also recommend cleaning up the intake side of engine with carb cleaner or equivalent: throttle body, Mass airflow sensor, EGR system, and PCV valve. Make sure EGR valve is operating.
If you have questions, please let me know.
