DigDeez need Help w/ decoding

[DigDeez]

Check Engine light came on, so I ran codes and here's what I got:

179-Fuel system was rich at part throttle Single Right or Rear HO2S

188-Fuel system was rich at part throttle-left or front HO2S

327-EGR feedback signal is/was low

332-EGR did not open/respond during test

336-DPFE sensor signal is/was high

412-Idle speed system not controlling idle properly (generally idle too low)

Now, I just cleaned out the EGR around September. This code was given as a stored code. Is there a way to erase stored codes?

Any feedback would help in this matter...appreciated...Thanks!!!

Disconnect the battery for at least 10 minutes, then run the codes again.

Also, I normally use Shell premium gas, but the last 3 out of 5 fill ups were with Mobile (2) and Marathon (1).
