Biff,
When the light first appeared, I checked the codes and got 12, 21, 55. I
pretty much ignored the 12 since I knew what it stood for. But now that you
mention it, I don't think I've had the battery disconnected recently (at
least not within 50 key cycles). So, I don't have a good reason for the 12
to have appeared the first time.
However, I did remove the negative battery cable to clear the codes in an
attempt to see if the light would come on again and how long it took. So, I
guess now the 12 should be there.
I'm puzzled as to why the light comes off and on while driving down the road
too. I've owned more than one dak too and have not seen this in the past.
My plan as of now is to replace at least the upstream o2 sensor (I'll
probably end up doing both) and see what happens. If that doesn't fix it,
maybe I've got a short somewhere like you said.
I'll let you know what happens. If you think of anything else, let me know.
Thanks agian.

Aaron, I have to leave for work now, but I'll check with a tech on my route
about what you said.
No, you wern't exactly clear at all on the light bit. And I don't like what
you said. I've run Dak's over 700,000 miles since Jan. 2, 1989, and the
occasional times that my lights came on, they never acted like that. Please
clarify that when the light came on and showed a 12, that you either did or
did not play with the positive connection in the previous 50 key cycles.
If you didn't, you might possibly have another shorting problem, connected
to the charging system. Did it possibly cause the O2 to short? I don't think
so. Electricals are tricky on Mopars. Biff
