Default low idle warm 90 jeep 4.0

Hi Guys:
Thanks for the good info. It's been too cold and windy for me today
to do too much, but I did tap into the O2 sensor and that seems pretty
non-responsive. The voltage slowly drops from about .45 to .3 volts,
motor still running and no engine lights. Shouldn't it be closer to
..5V? Even with that, it seems to run fine after its ran a few minutes.
Humm. Maybe that engine light is burnt out. Any quick ways to check
for codes, with a laptop or something?
Thanks!
Harry
