Check the fuel pressure regulator for raw gas being squirted through the
vacuum line into the manifold.  That would cause catastrophic
richness.  Unplug the o2 sensor -- if it runs ok then, that's probably
shorted.  Otherwise, I'd look for an injector that was stuck open or being
driven constantly (i.e. shorted harness or trouble in the ECU output stage
which grounds the injector line to operate the injector).  Look at spark
plugs for wet or gasoline smell... pull injectors and let them squirt into
a can one at a time while you crank (take off all the plugs so the others
don't operate while you're testing).  The injectors all fire at once, so
doesn't matter which one plugs into which wire...  Check fuel pressure.

Just some thoughts.
