My 03 Nissan Altima wont get over 2500 rpms


first check your fuel system, replace fuel filter, also check your fuel pressure regulator on your fuel rail it may be leaking internally if ok check your fuel pump operation. if your fuel system is ok then check for a restricted catalytic converter its a common fault I encounter with them. if that to checks out ok then have the ecm scanned by a shop or the dealer could be a faulty engine speed sensor or crank or cam sensor

It could be the fuel pressure regulator, but that can be determined by testing the actual fuel pressure in the fuel feeder rail. But first, have you changed the fuel filter? The fuel filter usually is clogged with debris whenever a fuel pump fails, so be sure to change that first.

Sounds like a ruptured diaphram in the fuel pressure regulator. Fuel is being sucked into the motor through the vacuum line. remove vacuum line off regulator and see if there is fuel, or odor of fuel in the line , if so , the regulator is bad. Good Luck

Hi,
I think you are on the right track. With the engine off remove the vacuum hose from the fuel pressure regulator and see if there is fuel in the vacuum hose or fuel is leaking from the fuel pressure regulator vacuum nipple,if so replace the regulator,check to make sure that the engine oil is not contaminated by fuel if so,change the oil and filter. Good Luck!
