when i first got my car from my mom, the CEL came on about 2 months later.....i never knew how to check it back then, and never knew about the .org.....i took it to the dealer, and they fixed it up....they said it was if you let your gas go down to much to often, it causes condensation or something like that in the bottom of something....anyone know what that was? is that evap canister? thanx
