Sounds like it's not boosting, and the engine is stopping you from doing damage - check the wastegate modulator (solenoid on the side of the engine in front of the turbo and under the air intake pipe). Also check that the breather hose has not worn through the wastegate actuator causing a vent to atmosphere. If these are fine, then you may have a vacuum problem - are the brakes ok?

Why want my 2002 Nissan Altima want rev over 2500 RMP?


It sounds like you have a problem with the AWU. Accelerator Working Unit, a fancy term for the gas petal. If it is not getting the proper voltage to the ECM it will default to a RPM like you are geting, 2000-2500 rpm. Find one from a junkyard and try it out. I would not shake anything that will just cause other issues.

Check engine light on. Will not rev up over 2500 rpm. Fluctuates between 2000 and 2500 rpm and runs rough. Upon first start, you can rev fine and it runs smooth as long as you hold the rpms over 3000. ...


Hi, there are a lot of things that could cause this behavior, so it would help us to diagnose your problem if you could get a scan of the OBD2 connector and send us the trouble code. If you live in the US you can usually get a free scan at your local parts chain.

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).
