I had a similar problem mine would hit a rev limiter at 3500 rpms. it would blow black sut out of the tail pipe. Ended up being mass air flow sensor/valorem sensor. almost 500.00 from nissan. fixed it though.

This is a classic symptom of a bad mass airflow sensor. Nissan designed this as a protective feature on the car. If the mass air sensor goes bad, the computer limits the car to a 2400RPM rev limit to prevent damage.
The sensor is under the center nose panel between the headlights. Take that off and on the back of the airbox (which fills this space) you'll see a pipe coming out that meets at a "T" with another hose going across and down under the headlights. That pipe off the back of the airbox is the mass air sensor (it has a harness plugged in).

Rent a scanner, read out any code(s), and pursue to repairs. It may be as simple as bad spark plugs and wiring, or worse, fuel problems from the injectors back to the fuel tank. A worn O2 sensor can cause improper fuel/air problems.

havent a clue ,from this old dinasaur to a liitle young mechanic sorry have a clue.You see here in spain they stick a nozzle up the exhaust ,and run engine at 2500rpm then check readings .Only vehicles from 2005 use OBDII in europe and most of these vehicles from this date use encrypted software so its a complete waste of time buying a snap on scanner because it would only read a funny code number that wasnt releted..Turkey for the dealer and bread and lard for the rest of us mechanics
