I had this issue - it was a failed O2 sensor (Driver side, Sensor 1 - which is the annoying upstream one), which was probably caused by a vacuum leak somewhere. It wasn't a consistent misfire, but after replacing the O2 sensor and checking all the lines/intakes/wherever there might be a leak, the misfire went away.
