D16Z6 Finally runs!!! In 90 hb, But.....

[Carnage]

I finally got my D16Z6 swap done in my 90 hb, I had some wiring problem's consering no spark, but that's over now.
Now motor start and seem's to runs great, but power seem to be a little SHITY when I took it around the block for the frist time.
I have played around with the distributer timing but still seem to lack on power.
( It's Like if the motor has a small miss)
I have a feu ecu codes poping up (6) (20)
Could this lack of power be because i still have not changed the O2 sensor.???(I snapped the Original O2 sensor (92-95) in the exhaut manifold.
Any ideas how to retaped the O2 sensor hole???/
Thanks

What ecu, distributor, obd, fuel injectors, and what o2 sensor are you using? Give us a little more details about how you wired it etc so we can better help you.
