well then the first thing you need to do is take it to a shop and have them run an OBDII scan on it. Or, you can go to Autozone and rent an OBDII scanner for free, and within five minutes, you should know exactly WHY your light is on. Simply posting HELP! My check engine light is on, does not tell us anything. Is the car still running oK?
It could be something so simple as you forgot to tighten your gas cap all the way the last time you got fuel.
