Question about 1990 Nissan 300ZX
Check if your injectors with the electrical meter with ohmmeter you should have around 12 ohms on each if you have above 15 ohms that's mean your injector is going bad it has problems ,easier way to check its if you will start the car with cold engine and go by the mufflers and if you will hear from one of the mufflers kinda shoots that's mean on this side of engine is the injector going bad ,the other things it might be mass air flow ground (-) wire which has some bad connection ,if not check all the connections on the ignition coils and injectors,check your spark plugs, and on the end if this problem will continue check your knock sensor!

I had this exact same problem and it was the Crank Angle Sensor and Crank Angle Sensor connector shorting out at High RPM.
THe solution was to put some electro-conductive grease on the connector the the sensor.
You'll find the sensor on the driver side near in front of the engine.

Its your maf sensor. ECU goes into limp mode when your maf craps out to prevent damage to the motor and wont go over 2400 rpm and its very precise. When this happens to american cars they start to run on a preset map the ecu has programmed into it and you'll just get really crappy gas milage. Personally I think that it just tears up your U joints because of all the lurching. I just fixed this on my 96 300zx n/a and i thought it was an injector,coil pack,fuel filter etc.

It might be a fuel injector going bad

Have already installed a new clear filter and have fuel in the filter.
