Outside of checking the compression and ohming out the injectors per Mark Haibecks procedure, I would scan it to see the sensor data. Of course a miss is obvious by feel and sound.

I kind of suspect a bad o2, one bum primary injector, or an air leak falseing one side or the other with a bad reading.

If you get in a bind, I do have a Tech1A that made fixing a couple of things on mine a lot easier- just have to arrange for a quick return as I wouldn't know what to do without it for long.
