I thought the same thing and went over the engine with a fine-toothed comb last Sunday (when I cleaned the MAF sensor) and couldn't find anything awry.

Simply unplugging the ECM for 30 minutes ALSO resets all of the data maps the engine uses. It defaults rather than using what it has "learned". So it may run differently for a while. That's why resetting a CEL with a scan tool is preferred.
Yeah, it runs like crap for the first minute or so after I reset. Then it runs wonderful right up until the CEL comes back on (anywhere from a day or two to a month).

One other point, the CEL only ever comes on at low speed, very light engine loads. Usually coasting, etc. Don't know if that is relevant.
