I recently bought an 2001 Impala and my check engine light came on!! I passed Marta/emissions 2 weeks ago and my engine is not making any noises or acting different.
Could it be something simple or a big problem???

you,ll have to get the computer scanned on it,there's so many things that it could be that i cant name all of them off,if you have it scanned this will tell you what set the trouble code and caused the light to come on,its probably just a bad sensor.but have it scanned,advance or auto zone can scan it and at least tell you what the trouble code is for it,then you,ll have something to work with,good luck with it.

First thing to check is your gas cap. Is it on tight?
