If you had the battery out for that long then you have either a "permanent" DTC (survives a power-off but can be cleared with a scanner) or you have a mechanical/sensor problem that the ECM doesn't like much but not bad enough to shut down. Edit: or it could be both.
For DIY diagnosing/repairing/modding, the FSM is the place to start. It can be intimidating if you are new to working on cars and Nissan sometimes has some weird nomenclature but it is what a Nissan tech will use (along with CONSULT software - if you have to ask how much, you can't afford it) if you take it to a dealer.
