rough idle, injector problem!!! help

[jarredd]

ok so i am having some issues with S13....

so a while back i was having problems with rough idle and loss of low end power and all that jazz.... after much trouble shooting and help from the zilvia family, it turned out to be a bad/faulty injector.

So i replaced that and all the symptoms went away...

Today, i was driving and i stopped at a red light, then next thing i know, rough idle and loss of power when touch the gas...

first thing that pops into my head, flashbacks of my previous issue....

So i pull all the spark plugs, one at a time, no signs of bad plugs...

Then i pull all the injector connections, and they are go extremely rough, all but one.... the same one as last time. the thing is brand new from about 3 months ago. I would assume that it would last longer than that. So i am wondering what your thoughts are, could it be faulty/short wiring on that injector? if so, how could i fix this? rewire?


the issue, rough idle, around 450-800, putt putt putt exhaust, no power when accelerating, smoke/foul smelling exhaust, cant tell what color cause its dark outside...

anyway help is much appreciated!!!!!


thanks in advance,

new update...

i checked the wiring, looks ok, dont have a dvm or anything to test the current/voltage though

wiggled the injector, started my car, and it seemed to idle fine in park, as soon as i shifted into drive, the idle got really rough and would stumble every second...

like it was hiccuping every second until after about 15 seconds, it would just stay at around 450rpm and putt putt putt putt putt....
