Well, it was bound to happen sooner or later. My 91 Civic, 1.5 165K on it. I was driving and it ran real rough and the check engine light come on. I pulled over, stopped it and when I restarted it, the check engine light turned off and it is running just fine.
Questions
Does it store a code indicating the problem?
If so, how do I pull the code?
All help would be greatly appreciated.

Pull back carpet from passenger side footwell (undo from button), count blinks - they are one at a time. The codes are listed on the FAQ link. GL
