I was driving along today and check engine light came on. This happened recently about 4-5 months ago, and nothing seemed to actually be wrong.. just a routine maintenance sort of thing. Turned the light off through directions given by someone on this site. Now I'm just wondering if this is something that should be a true concern. Nothing seems to be wrong, nothing funny in the last few weeks that I can recall. I'm getting it checked tomorrow, just interested if anyone has a similar story that may be helpful!
