get a bently book if you dont have one
idles crappy well is is running on 3 or 4 cylinders start there when swap
the plug wire and see if that help the dead cylinder then compression test
next check the injector to see if its spraying
the pin test in the bentley book is needed. checking just the sensors is
only part of the story. the wiring harness and the sensors together is a
good place to start. disconect the 02 sensor until the cure is at hand. once
the exhaust is full of fuel the 02 sensor just fouls until the soot in the
exhaust burns off
