Hmm, maybe I should have described it differently. I don't actually think
the O2 sensor system is working wrong. Maybe if I just described it like
this:

The car idles badly (misfiring, small backfires, engine shaking), but
doesn't stall. Reduced power on acceleration, with the same misfiring,
etc. At some RPM (depends on the gear; 3000 in 3rd gear, for example)
power returns suddenly and no more misfires. If I stay at this RPM all is
well. If I'm decelerating the problems don't start again until I stop
decelerating (i.e., stay at a specific speed or speed up again).

That definite cut-in of power and the misfires is why I think there is a
problem with an injector.
