Question about Cars & Trucks
Sounds like it could be low fuel pressure caused by a weak or failing fuel pump.You will need to check the fuel pressure and if its not within the specs replace the pump and filter.

As a factory Nissan trained Technician with dealership experience - it can be many things, but it sounds alot like a mis-adjusted or faulty TPS, and/or a faulty IAC(Idle air control) valve - I'd try the TPS and set to appx. .50 vdc (.47/.49) Volts DC and if that isn't it, I'd definitely look to the idle air control valve ( allows for air bypass - sometimes called bypass air control valve). May then need base timing and idle set at shop with OBDII ignition disabling option, for seting timing and idle, otherwise computer won't allow proper setting...then if connector to IAC is OK - should be just fine...
