I have a 2002 nissan altima 2.5 4 cyclinder. My wife was driving the car when it started to sputter and miss. The car would not go over 20 m.p.h.. The check engine light is not on. The car will start and idle just fine. Wnem you rev the engine up it does fine until it reaches 2000 r.p.m. and it will spit and sputter like it is starving for air. I was told that it could either be the fuel pump or the mass air sensor. Also does the fuel tank have to br dropped to access the pump or can it be reached through a trunk panel. Thanks!!!!

before you replace the pump, be sure that its not good, check the pressure first
then check the mass sensor (that sensor its expensive!)

Suggested Repair

Check fuel pressure before replacing the fuel pump, then test the mass air flow sensor, which is expensive to replace.

Conversation Summary

A 2002 Nissan Altima 2.5 starts and idles normally but sputters and misses above about 2000 RPM and will not exceed 20 mph, with no check engine light. The owner was told it could be the fuel pump or mass air sensor and asked whether the pump requires dropping the tank. The expert advised confirming fuel pressure before replacing the pump, then checking the mass air sensor.
