I was out driving tonight and my SES light came on and the engine feels like it went into limp mode - very choppy, like it's only running on 3 cylinders. I kept the revs down and drove it home. Since it's the weekend my dealer can't see me until Monday. Without having a code scanner, does anyone know what typically causes this? 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?
