I hate to be the first do have done something stupid...but I seem to be good at it! Last night on my way to work, I passed someone on a two lane highway. After passing I noticed that my check engine light had come on. So, of course, I freaked; figuring I had already FUBAR'd the new car. So after reading the manual I made the one adjustment it suggested (ie tightening the gas cap ?!?!) and now I'm not sure if I should drive it anymore. The manual said if it's a gas cap thing, the light will go off on it's own in 2-3 days...then in a previous sentence, the manual states that you shouldn't drive the bugger at all if the light comes on. Anyone have any ideas? I am, of course, calling the dealer but I would like some real world type advice.
