Take to a nissan tech this sounds like a bad tps sensor throttle position sensor or a cruise control issue . Your problem is likely to serious to deal without a code reader an having the vehicle in front me. Think of safety first here or a accident.

Engine dies out above 2500 RPM, picks back up at 2000 RPM


That's a characteristic of Nissan engines when the mass airflow sensor is not working. My 1990 300ZX was set up the same way - when the mass air sensor fails, the car won't rev above 2500RPM in order to safeguard the engine. Get some air intake/throttle body cleaner and clean the mass air sensor. Get some electrical contact cleaner and clean the electrical contacts on the harness plug that plugs into the sensor. If that doesn't cure the problem, you'll need a new sensor.

The mass air sensor is in the 3-4" diameter pipe between the airbox and the throttle body.

1985 Nissan 300zx will crank, run, and diesel until it dies


YOUR problem is you have water in the engine as that is the only thing you can get apart from brake fluid that can cause white smoke OR steam out the exhaust or white steam out of the breather so check the dip stick it should have water beeds on with the oil or if you take off the filler cap it will have white oil on it,, so then drain sump and fit new filter and refill with 20W 50 and away you go..Have a goodday Ron

92 300zx rpm will not go over 2500 rpm pops from intake


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).

Can you not get any RPM out of it above idle, or does it rev to a certain point (say, 2400 RPM) and then refuse to go higher? If it's the latter, where the revs stop at a certain low point, check the mass airflow sensor out - on my 300ZX, a bad mass airflow sensor triggered the computer to limit RPM to 2400 to keep from damaging anything in the engine.

My KA24E SOHC will not pass 2500 rpm while driving or just reving.


On my 300ZX, a rev limit of 2400RPM indicated a failure of the mass airflow sensor. That was a Nissan safeguard, and it's probably the same on your 240 - check that out, clean it with electrical contact cleaner, and if the problem doesn't go away, replace it.
