Hey, guys my computer threw an injector leak code and the car idle is bouncing 400-900. I cleared it and it came back. i went and got some new seals i installed them and OMGWTF the first injector is leaking like crazy now, thought it was a bad injector so i grabbed a used one and another two new seals, installed it and it stopped leaking, but the engine wont go away. Ive cleared and it comes back, Ive even driven it until it does away by itself but it just keeps coming back.

I believe read somewhere to take off the fuel rail with the injectors and leave it off with everything plugged in any of them or all start dripping with the key in ON position that = bad injector. Well i went and tried that and the 4th injector in the very back just blew off the rail. and i didn't even bother looking for leaky injectors. So i put the injector back in the rail now the 4th injector is leaking just like the first one was. I'm going to buy new seals ONE MORE TIME because i didn't use Vaseline on them like i was supposed to the first time (so maybe there tearing when i jam them in or back in just like the 4th injector).

SO.... i want to fix this problem, its annoying. When the code first came up none of the injectors were leaking fuel out of them, or so i believe. But i did smell some gas once in a while. Is an Injector leak code even cause by an injector leaking fuel from between the top of the fuel injector and fuel rail? or does the plunger not come all the way down inside the injector causing it to leak into your cylinder, foaling your plugs and causing the bouncing idle, (until the first 15 minutes and the cars all warmed up then the idles fine.) because that makes a whole lot more sense to me than the other stuff, im just getting really pissed off and fed up with this, and my mind IS Just everywhere right now and i cant think straight anymore.
