Ok, cars never givin me problems when it comes down to the engine running. I started my car up 2 days ago and it just sputs. its like a constant sput no matter how fast/slow im going, seems to not be as hard of a sput after around 3500RPM but is still there. When sitting still in drive it sputs hard enough to shake the car. i changed the fuel filter, nothing changed. I have narrowed it down to 4 possible things, but im not sure and would like some opinions to see if this has happend to anyone else.

1) Plugs/Wires but they were replaced around 15k miles ago and look completly fine.

2) Somthing to do with the intake, specifically the mass air flow sensor(btw i played with the wiring for the MAFS and my car stalled, got in there cleaned up the harness and still does it, this does wory me but i still think it may be somthing else.

3) Wet Gas??

4) My cars ****ed

id say injector to, i had the same symptoms about a year ago and it was a bad injector, and i did the same thing you did and replaced the fuel filter hoping that was it

Ohm test your injectors. Should be between 10-14 ohms

im am pretty well rounded when it coems to cars, i honestly do not know how to test injectors, whenever they went before i would just junk the car. (past cars were all pontiac grand prix or grand ams that i paid under 800$ for) but i have come very fond of my maxima and i love it to death. i redid all of the body work and interior work with plans of doing an engine swap here in a few years, but it needs to last me at least threw the winter the way it is. so how do you go about testing injectors.

You need a multimeter. Set it to a ohms setting, something like 100 for example. Unplug the injector connector and put a lead on each pin on the injector. Pretty simple. Like I said a good injector is between 10-14 ohms anything out of that range is a bad injector.

after 5k miles No.1 and No.3 were infinite.....the solenoid has an open in it......

Its not really possible to test the #1 injector on the VG engine, because it sits under the intake manifold.
