EFI conversion Need help FAST!

[Fostang]

Finally got around to doing the EFI conversion in the 67' fasback. Sounds real mean on start up. In cold start up it will idle just a little rough and I won't notice anything wrong. Then once it warms up and I shut it off It'll be hard to restart once It starts I hear a click inside the computer and it cuts out like its about to die and then comes back if I reverse the left and right oxygen sensors it'll die out when you hear that same click. I also tried disconecting the ground on the oxygen sensors and then starting and it idled a little rough as during a cold start up but if I try grounding the oxygen sensors the problem of the engine wanting to die will be back. Also pulled the plugs and they are black. What could be the problem? Any ideas on what I should check? Also I'm confused if the right oxygen sensor is the drivers or the passengers side. :shrug:
