Hi Folks:
  Just a tech question, really.  I just read that the oxygen sensor in
this jeep is titania, as opposed to zirconia, and therefore doesn't
generate voltage.  I've read the computer puts 5V through a fixxed
resistor in series with this sensor.  I think it's saying the computer
is looking for 2.5v as a good voltage.  Also, it mentions it going from
0 to 2.5v.  Mine seems to pulse at about a 2 seconds on, 2 seconds off
rate. It's not at 2.5V on though, but more like a half volt (like a
zirconia?) My Jeep seems to run smooth, but maybe running a bit rich,
and I think ignition retarded.  Might this be a temperature sensor
going bad?  Temp gauge reads normal.  No indicator lights, but I think
this computer might be rather 'old-school'.  It was doing this thing of
stalling when it was warm-started, which would fix itself after
restarting, but that went away when I had some battery problems and
lost good contact with the terminals. (computer reset itself?)
  Is this computer behaving?  Are these voltages normal?
Thanks!
