if thats the case your plugs are probably fouled...
did the system get richer as time went on or was it rich from the get go?
your o2 sensors could be fouled as well.
i would suggest taking it to the dyno, to be sure.

At this point a dyno would be much too expensive for me. The plugs could be fouled, same with the o2 sensors. We pulled the plugs out just a few days ago and had multiple sources independently confirm that they looked healthy. I have not removed the o2 sensors though. Would there be a visible sign of fouling?
It was a little rich from the get go, but definitely got richer as time went on.

If you look at the injector wires and o2 wires they have a code writen on them that specifies which cylinder that they are suppose to be on. (pretty snazzy in case wires go everywhere)
I feel that is your issue.

I didn't know that they had codes written on them, that's pretty cool. What exactly is written on them, and how do I match them up correctly?
