Ok guys now the fucking car won't go pass 2500rpm it starts 2stepping lol. Just changed the fuel filter and man was that shit dirty. It's still doing this so ima change the fuel pump. Hopefully it's that. If not any other suggestions? Even when it's on neutral and I gas it, it won't pass 2500rpm. And it also reeks of gas as well

sounds like a maf for sure

Yep so far it sounds like the MAF, if the MAF is not plugged in the car goes into limp/safe mode. The computer allows you start and drive but will not allow you to rev pass 2500krpm.

Thanks guys. Exactly where is it located lol...and I also have the tool that measures the pressure of the fuel...by any chance does anyone know the normal fuel pressure for the dual ka24?

For real?^

It's what your air filter is bolted to. If that doesn't help, google

You should be asking yourself, how come everyone agrees the answer is mafs?
Then you should look for an FSM for your make and model.
The first thing you should do when you have problems is, pull ecu codes!
You'll most likely find you have a code 12, 34 and probably some others stored up in there.
Before you ask what code 34 is do a search for Nissan code 34, then come here and ask where that sensor is, I know redundant if you have the FSM, but you're allowed to know because you showed some initiative!

Alright so the fuel pump was not the problem, but good thing I changed it along with the fuel filter! The sock on the pump was black and had parts of metal in it!!! Then the fuel filter leaked black gas!!!! Everyone was right, it was the MAF. Wires were pretty chewed up so I just made my own plug and now it's fixed
