I have a 97 contour SE. I scanned the forums but no answers. On the way home from school a couple days ago my check engine light came on. It was a hot day and all, but I popped the hood and all vital fluids were at perfect levels, the air filter was clean, and everything looked intact. I ignored the light for 3 days but now I have to get it scanned at a shop. There is no apparent loss of power or gas mileage either. I bought my car 5 months ago and only major maintenance done was new plugs at 82,000. CEL came on at about 84,500. Is it true that CEL's can come on for no reason when your odometer hits a certain mileage? Otherwise I am lost and asking for any advice or things to check before I take it to the shop. I hope its nothing major cuz I'm kind of cheap.

Thanks.
