evap purge

my check engine light came on recently and i ran a diagnostics on it it came back that it was the evap purge. any clue as to what this is and where. i thought i might of left the gas cap off or something but after two days it came back on.

the evap system is behind the SC (in 97-+ GTP models), its a little cylinder (like) with vaccum lines, check the vaccum diagram in your hood. If the evap damaged, its too cheap to replace.

Hope this helps

I think it look like this..........~Larry~
