It is true that it will self-learn after it runs for a certain period of time, it's just makes it easier if you clear the self-learn w/ a scan tool or Consult II, so that you know the results right away if u fix it or not. I would check ALPHA readings first if you have access to a scantool or Consult II, possible u have an AFM problem. If ALPHA is ok & there's no codes, could be an ecu problem. Best bet is to swap a known good one, I believe it will need to reprogram the key everytime u swap ecu, w'c can only be done at your nissan dealer.
