First thing I think would be to get it plugged into a nissan consult reader, see what the sensor outputs are all doing which will give you clues where to start looking.
There are a few possibilities but instead of just guessing and being a swappatron (copyright intrade 2014), it will help if you knew what the computer was seeing.

What # 2 has said is your best bet, cheaper in the long run if you are not sure what you are doing.

Its probably got a massive air leak somewhere in the intake. Check all the hoses and pipework first.
