car leaning out after injector install
i wired in my stock injectors on my turbo b16a2 and now when i give it gas it bogs i cant drive the car at all. it bogs and wants to turn off. also i notice that my a/f gauge goes from lean to rich back and forth the it will go to lean and the light on the a/f gauge will just turn off. what can it be??? help also my friend hooked up his snap on diagnotic computer and when it goes lean both my o2 sensors read 0 voltage and i get no injector pulse so this means it has to be wiring, how do i troubleshoot this problem???

Wow. The amount of things that could be wrong here are astronomical. Some more detail would help verify, but the car could be leaning out and then go into limp-mode. The injectors may not be seated correctly (needs about 2 hrs to fully seat), you may have damaged a connector on the injector(s) etc etc. Some more detail would help narrow down the possibilities, but these are the first few things that came to mind.

its wierd because my o2 sensors just lose complete voltatage and my a/f gauge just goes all the way to lean then the light just turns off. also when that happens i also lose injector pulse. i dont think its going into limp mode because i have no check engine light

My fault. All that crack must finally be getting to me. I'll edit to suit...

my grounds for the injectors? oh, i also cut off my ecu plugs that plug into the ecu and tapped in some other ecu plugs because my old plugs wires had been cut too close to the plugs when i installed a vafc.

Engine ground.
Injectors fire off of ground
Could be a short somewhere causing the problem

Wtf would 2 hours do? If they are not properly seats are you implying after 2 hours they will magically seat themselves?

That should be obvious to even a complete idiot such as your self. The injectors being applied against the rubber o-rings and then against the injector bungs in the manifold are not seated properly. The pressure of the injectors on the rings hasn't made their indentation yet so as a result the seal isn't as tight. There's usually a white vapor (fuel mist) when they're not seated correctly. So to answer your stupid *** question which is presented in a condescending manor, yes, after about 2 hrs the injectors will "magically seat them selves".
Trust me man. I'm not pulling this stuff out of my ***.

Re: car leaning out after injector install (bluesi00)
Sorry, was just being a jerk to night.
Ive been told by many sources injector wires do NOT have polarity. I certainly didnt worry about it and Ive wired in several sets of injectors w/o problems. I would take a step back first and make sure the injectors still work. You can jump the pins on the injectors to a few D batteries taped together. The injectors will click as they are opening and closing if they are in working order.

That's fascinating. Ask me what difference your ignorance makes to me? Someone else already attested to it being true from their own experience, but you still won't accept it. What ever you say.
I'm just curious, if ignorance is bliss then why are you so mad?
