Downtown LA Nissan never figured out what was wrong with my car, not even the specialist that Corporate Nissan sent. They replaced ignition coils, short block and fuel injectors. They had my car for over a month total. If you guys keeps having this problem, just have Nissan buy it back. They bought my 40th back despite me buying it used but still under factory warranty and now I'm rolling in a 2013 Nismo
