charcoal emmision cannister?

[pumpkin]

A charcoal canister is only for evaporative emisions. It has no effect on mpg's, or performance. Where I live I am a licensed air care tech. Air care is what they call smogg testing here. As far as testing for the canister goes, since when working properly, has no effect on tailpipe emisions, as far as the testing goes. Short of testing all the components in the system, there is no test. Here they just visually see that it is in place and looks to be properly connected.
