I doubt it's the MAF (both banks would have problems) or the O2 sensor (it wouldn't be just one cylinder. A single instance of misfire won't hurt anything, the ECU likely shut down the offending cylinder (the flashing light says Hey, shut down so I can reset) to preclude damaging the cat, too.
I'd suggest getting it on a regular scanner that can give you some real-time feedback and LTFT data. If the LTFT data look good, you can further discount the MAF.
If the scanner can isolate cylinders, you may be able to truly pinpoint the issue.
I'd probably be tempted to take it to a good indy that has an appropriate setup (doesn't have to be the SDS) and can help you diagnose it. Either that or start throwing parts at it, which will get expensive, frustrating and time-consuming in a big hurry.
