First things first: If it's a
flashing CEL, you
DON'T want to drive it, at least not very far at all.
Mine only flashed very briefly. I ended up taking it up to a place in Twinsburg, OH ("Steinel's Autowerks", a place I highly recommend from what I've heard and from what I've seen in person). He told me the misfire was brief (a few seconds) and that all kinds of harmless things could have caused it. He reset it (the CEL) and told me to run it hard driving home---blow any nasties out of the system.
I did so, and the CEL hasn't recurred, at least not so far. It is, and has throughout, always run fine.
