Does the 2011 have a DPFE sensor? If so where is it located? Codes are lean bank one and two and random misfire. Suggestions I have read online are replace DPFE sensor. I don't think maybe there is one on a 2011 6.2.
Any other suggestions for this problem, or others who have had it and had it fixed. Other things I see are clean the MAF sensor. Look for vacuum leaks.
Thanks in advance.

 

The lean codes tell me to look for a vaccum leak. how many miles? maybe it could use some new plugs
