2 times I have had my CEL come on, then turn off by itself. Believe it or not both times it came on, I was in the drive thru at Taco Bell!!!!! Both times it was the same O2 sensor.
Intermittent CE lights can be caused by dozens of things. A good porsche mechanic who knows how to read a PST tool hooked up to your car running at idle and up to temp can diagnose a lot. My mechanic does this with me a lot. He "watches" the engine run on the computer and then points out the levels of each sensor, etc. and tells me what's going on. It could just be a tank of bad gas.
If it comes on again, you should get it checked out!

02 sensor must've sniffed some funky gases at the Taco joint.
