yeah some research i did shows that the O2 sensor going bad is one of the causes for this. i just find it odd that it only happened once and all seems to be well now though. but i'm going to take it to the dealership when i have some time and see what they say since it's under warranty until the middle of next month.

I had a BMW that did that when it needed new oxygen sensors.
I will give you my stock response to 'faulty oxygen sensors caused massive drivability problems on my OBD2 car':
Bull. Shit.
Faulty O2's generally do a couple things: they put out little to no signal, or they lack the proper sensitivity (do not switch fast enough).
On a vaguely modern car, there is nothing an O2 can do that will cause an engine to run like complete and utter trash. I really don't feel like getting into the particulars of how O2's work, how the feedback loop is used, what fuel trims are, et al. If someone wants to know why claims that faulty O2's cause massive misfiring and/or lack of power are utterly asinine, you'll have to go do the research yourself. There is no debate.

Flashing CEL = do NOT drive the car, you're getting continuos misfires *. Unless you like paying for new cat converters among other things.
* bosh motec has the threshold around 10 misses in 1 second
While I am in agreement that an O2 sensor generally cannot cause misfires... Why are you so hostile all the time? As if you take everything like a personal insult. People are just trying to help, nobody is being malicious here.I will give you my stock response to 'faulty oxygen sensors caused massive drivability problems on my OBD2 car':

To expand on what phuc was trying to say... An O2 sensor helps the ECU determine the fuel ratio. But think of it's influence like a very fine tuning. For there to be a fuel ratio based misfire, you'd have to have an extremely lean condition (or I suppose a rich condition, but then it'd be flooding, which is quite different). The amount of fuel the ECU regulates based solely on the O2 sensor input really cannot make enough of a difference.
I'm sure there are exceptions, so I'm not calling those people "asinine" who say an O2 sensor fixed their issue. I'm speaking in general here.
That's not totally true, whack o2 signals will make the additive and mult trims completely fucky to the point of misfire. Case point, swap the bank 1 and bank 2 o2 signal leads and see what happens.
