Second Try - GTi-R Engine blowing Black smoke

Hello fellow se-rians...

I'm trying to get my GTi-R engine running and am having a big problem with
gas: Too much! I'm running the gti-r ecu, maf, and o2 sensor, and for some
reason it is running very very rich. I have tried with no luck to remove the
o2 sensor from the housing, and it won't budge..
 I've checked the voltage on the MAF and it's fine, and have done the
check on the TPS... as far as I can tell..

I'm having a problem w/ the tps actually. I'm not sure how to get the
reading from it.
http://www.se-r.net/engine/tps_voltage_adjustment.html explains how
to do it, but I dont quite understand it. It says to "hook the positive lead
through the back of the harness" but there is no back of the harness?
I'm not sure if I'm looking in the wrong place or something but I can't
seem to figure that out.

With my engine there's the TPS and a plug goes into it which is connected
to a short lead which then goes into a smaller 3 wired plug and then that
plugs into the wiring harness. Is this how they all are? It seems rather
strange.

Also, I know that the GTi-R's tps goes backwards to the SE-R, so I had to
swap the wires in order to get that to work. What if I wanted to just
install the se-r TPS, would that work? I'd have to move the lever to the
other side and then install it.. would I then be able to swap back the
wires,
or leave them the same?

Is there any other reasoning behind why it would be running so rich? I mean
there is black smoke coming out of the exhuast at all times.. I'm sure
that's
not good for things. I also noticed that the oil smelled a little like gas.
I
changed it as soon as I smelled that (not more than 10 miles on the engine)
so I think/hope it'll be ok.

Do you think it might be the o2 sensor? I'm going to swap that out and see
if
it fixes the problem as well..

I really need your help here guys! I couldn't find much in the archives
aside from Frank who was having the same problem.. I couldn't find a
reply.

Thanks guys!
