Both of my girls have the exact same car (2011 Nissan Sentra - one black one silver) and both cars have had the exact same problems back to back, started with mass air flow changed sensor, filter, hose, intake gaskets, then its been back to back with both cars on the misfire issue. The coils and plugs have been changed numerous times, and I ran seafoam thru gas - it fixes it for a bit but here we are not even a year later and right back to the same problem again with the misfire. To fix this problem you have to take the whole intake apart just to get to the plugs and coils. What use to be a 15 min job has turned into two hours. I have worked on both cars so much I can do it with my eyes closed...
