Ok, so let's cover all outstanding points:
Brian:
as the matter stands, the question remains unanswered. Even w/ flame-bait like this one everyone is eager to up the post count here, but not there. Wonder why that is.
Pete:
I have a life thank you.
Matt:
Thanks for understanding. My reasoning was exactly as you pointed out.
Jim:
I appreciate the effort. I simply questioned the motives. These are two different things and they do not contradict each other. I might've sounded irritated, but that's not how I wanted to come across.
Roger:
pan intended
I posted in General forum consciously. Knowing that people react to keywords rather than the context where these keywords are encountered in, I pointed out in the subject line that I would like this question to be treated as General because that's what it was. I thought it ought to be enough. Apparently I was wrong. So while I would like to avoid prolonging this thread, I will say it again, I fail to see the reasoning.
Now somebody please answer my question: under what circumstances can a PCM store trouble code w/o MIL on.
FWIW, I passed NJ emission today morning, but then code is not OBD-II generic, so they might not even see it.
