2011 Nissan Altima,
Ok. From what I've read this is a common problem with these cars. There is a pcm software update that would need to be preformed. You would need to take it to the dealer for this. Clean the Maf (mass air flow) sensor. You can get a can of maf cleaner at your local parts store.
As for right now nissian is unsure of what is causing this problem and they are currently looking into it. Here is a link to what others are experiencing with this problem. http://www.nissanclub.com/forums/2007- 2012-nissan-altima-discussion-2-5-3-5/336081- 2011-coupe-p0101-maf- problem.html#/forumsite/20547/topics/33608 1
