I would say to ohm out the injector harness. There's a link to the how-to somewhere- It will take about an hour, but you can meter out the injector resistance to find the worst injectors. If you even have one bad one, plan on doing that for sure. It sounds like one other thing might be wrong as well.

One bad O2 sensor on one bank will also cause issues...it would save a ton of time if you can meet up with somebody with a laptop program or the factory tech1 scanner to look at operating parameters real-time when the engine is running- not just reading code history.
