Rough idling. I pulled out second spark plug wire, and made no difference, all the other ones made the idle worse and almost shut off engine. checked distributor, new plugs wires, still running rough. it used to this randomely, now its always and the car has no power. something with the second cylinder, it moving, as i removed the spark plug and heard it. but i dunno what 2 do!

Try unplugging your fuel injector on #2. Checked for spark at #2 plug wire?Sounds like a injector to me....

[S3t0_S13]

yea #2 is sparking just fine, new wires and plugs too, i have yet to try the injector, it runs a little rich though, i can smell gas from the exhaust though, think it could be anything else?

yes could be burnt vavle. You need to check the injector just swap the number one and two injector if number one is dead then you know you have a bad injector if not then do a compression test on number two.no compression then do a leak down test .

how do u remove the fuel injector?

i took off the silver cap with the two screws, and twisted it, but it wont budge!

alrite read up on it, how to pull em out wit vice grips, im gonna do that right now, so i should switch the fuel injectors around and see what happens

BUT.... i pulled out the top part that has red and black wires, maybe the input for the ecu to tell it to spray, and nothing happened, it still idled horribley

someone please tell me that its just a bad injector

you can put a diode light on the injector connector to see if your getting signal from injector if you are then swap the injectors to see if problems moves to number one like i said earlier, if your not getting signal then youll have to backprobe your wiring to see why your not getting signal to that injector. DO A COMPRESSION TEST LIKE I STATED EARLIER THEN DO A LEAK DOWN TEST IF YOU HAVE COMPRESSION IN THAT CYLINDER TO SEE IF YOU HAVE A LEAKY VALVE(WHICH WILL CAUSE A DEAD CYLINDER)

I highly recommend that you replace the o-rings with the injector and be very careful installing. I had the exact same thing happen and tore the new o-ring ... ended up bringing it to nissan to replace the o-ring because im lazy.
