I was coming home from a snowboarding trip when all of a sudden the engine light comes on and I felt a strange vibration whenever I stepped on the gas. I pulled off to the side and tried restarted the car, and noticed it accelerates poorly and the engine vibration gradually got a little better as I sped up, but still very noticeable. It also seems to kind of chop as it is starting up.
I have changed the transmission fluid, oil, and spark plugs, and this still is occurring. Any idea what it could be? Something must have broken for it to occur so instantly, but I have no idea! ><
