Hi there. Yes, I forgot some information. I have had the codes checked, and it has generically pointed to misfiring on cylinder 3. My mechanic did some wire switching to make sure it wasn't a plug or wire, but the second occurence was also cylinder 3. At this point, he was fairly convinced it was the ECM because of how good the car ran when it was "not" missing. Also, he was driving it during one of the "cel flashing" episodes, and concluded that at that moment the car was running perfect - not missing at all. Of course, at other times it does miss - badly.
I should also mention that about 8 months ago, or slightly more, I had an O2 sensor fail and replaced it. That one was properly diagnosed with the engine light code.
