Car not running right?

[droppedspyder]

K, just put my 4g63 head on my 4g64 block. Turbo is perfect, all lines ran. Got it running last night, but my battery didn't have enough juice to start it. I had to jump it with another car. The problems came here. Took it for a drive, it seems to hit a fuel cutout and sputters. I don't know if it is because my second o2 isn't hooked up to anything. I still need a downpipe. Also, my car will not stay started, is my idle off? What other things would cause this. It seems to be running rich when at low rpm's then lean at high rpm's. Still is this a problem caused from my o2 sensor?

Yes this is a problem with the o2 sensor. Put it in. Hook it up, whatever. Also try disconnecting the battery for about five minutes to reset the ecu. If something was tweaked in your ecu while jump starting disconnecting and re-hooking would one way. make sure that the battery is charged so you dont have to jump it again.
