Injectors, very strange problem
-okay, as some of you may or may not know, my #1 injector is 'dead'. anyway, two weeks ago, i did the pull nd clean technique with that injector terminal. yes, it was corroded. i had cleaned it, but when i went to start it up, NO CHANGE. but throughout this week, my maxima runs as it did when i bought it back in november.
Whats Up With That??

Cleanup doesnt mean contacts are healthy. If your problem was bad contact, then now u have it ... until May ? ... (cut/solder the wires solid or get new pins (=injector), connectors)

what do the months april and may have to do with anything??? and plus, its not EVERYDAY. its mainly 6 times out of 10 during the week. im changing the injectors on monday anyway, so i should be able to see a difference

Focus on the intermittent contact issue - its dancing in tune with microsoft stocks and the calendar. Soldering the wires solid - or getting new contacts - will clear that vibration controlled contact problem.

it's one of the more unusual symptoms of injector failure.
look at a light bulb. see the filament inside of it? when a bulb "dies" that filament will typically break at some point. on occasion that break will touch together again and weld/solder itself closed. that fix usually only lasts a little while, but it does happen. the same thing is happening to your injector.

Yep had this problem with one of my injectors, when the engine was running rough, it measured about 100ohms, after it warmed up, sometimes it would smooth out and run fine, if I measured the injector in this state, it measured about 35ohms. The weird part is the injector was either working ok or not at all, almost like the resistance of the injector reached a threshold where the ECU recognised it as ok and started driving it again, even though it probably wasn't performing to spec. Both measurements are well out of correct range. I replaced the injector and haven't had a problem since.

im gonna be changing the injectors/fuel rail tomorrow anyway, so it really doesnt matter anymore to me, i was just wondering why.
since im doin that, i was told i needed a plenum gasket and reccomended new o-rings. i remember seeing a write up about it somewhere, but i cant find it anywhere.
is there anything missing????

To be safe, get the upper and lower plenum gaskets, and per Wayne's suggestion which should be quite helpful, before installing the new o rings, rub vasoline or petroleum jelly on them. And dont pinch or damage them.

get injector o-rings from dealership, they are cheap and better quality than any autoparts store.
Like i said in someone elses post about the o-rings, I did my front 3 injectors, went through 9 autoparts store o-rings in an hour, then got 3 from dealership and they didn't get pinched....yes I lubed the **** out of the autoparts o-rings and they still tore every time

just to make sure we are deffinitely clear, i have the VG30E, and i've heard of only ONE plenum gasket needed. a local mechanic i've known for a while has worked on problems like these on maxima's like mine, and he clearly stated i needed only 1 plenum gasket.
