Q: The Check Engine Light went on, and then went back off
Yesterday, my Check Engine Light went on. I don't know if that had anything to do with it, but it happened shortly after I rode over a very bumpy stretch of road at highway speeds, to the point that I thought I had a flat tire. However, this morning the light did not go back on. I looked under the hood and checked the motor oil, and everything looked fine. Is this something I should worry about, or should I just ignore it?
