So, I'm driving on the highway and I go to pass a car so I tap the tiptronic to downshift to 4th to gain some speed, and I was around 3500rpms surging pretty hard past the car and then the car lost power (car sputtered almost like a spark plug or coil went dead) and dropped to about 3000rpms. The check engine light immediately illuminated as soon as the car lost rpms, and I basically coasted off the exit. When stopped at the traffic light the car was shaking and vibrating (the gear selector knob was shaking back and forth), and the car felt like it was running on 2 cylinders. I got home and let the car keep running and the exhaust sounded like it was missing a beat, and the engine was distinctly throbbing. I got my scanner out and P0302 (Cylinder 2 Misfire), and a fuel trim malfunction in which I cannot remember the code for. But after hours of sitting I started the car back up, and drove it around and it was fine. No check engine light, no vibration, shaking, the car sounded smooth again. I still don't understand how this happened, and how it seemed to correct itself? Is this a sign something is about to go seriously wrong?
