My last fillup was about 65 miles ago, 93 octane...I would think if it's the gas I would have noticed it sooner.

I've turned the car off and started it again a few times and the light is either there when the car is started, or returns within about 10 seconds. Is there any easy way to do a reset of the ECU and see if it returns? Anyone else had this happen?
Sounds like a misfire, take it to the dealer and have them check it for codes. Once the figure out what cylinder is the problem have 'em check the coil packs/spark plugs.
