from your description the engine is running to rich and you have gas fouled
the plugs, O2 sensor and the exhaust system. I would suggest you do an oil
change to remove the unburned fuel from the crankcase. Then I would do a
compression test while the plugs are out and then replace the plugs with a
fresh set. Next I would disconnect the O2 sensor and run it for a couple of
hundred miles that way to clear out the soot from the exhaust. The O2 sensor
is fouled to the point that it is most likley making the injection run full
rich replacing it wont change anything as the new one will foul in a few
miles. The ECU will use its base setting and you can run it this way with no
problems. The European 2.1 engines with digijet injection do not use an O2
sensor due to the leaded fuel used

Subject: Billy won't run

> I drove around for about half hour last night and Billy ran worse and
worse.  By the time I got home it would barely run.  This morning when I
tried to start it, it starts, revs up, then immediately dies.  No way to
keep it running.  I pulled the plugs and they were wet and black (less than
100 miles on them).
