You have to pull codes to get the scoop on what is setting it off...failure of one or more emission control components will set this off...

...that said, other than the obvious issue of a gas cap that isn't secured properly, the only "guess" diagnosis would be either an oxygen sensor or the MAS or mass air sensor. My money is on the MAS failure. Part goes for over $600 I believe.

Again, the codes will tell you what emission component is causing the problem.
