Couldn't find another post on it. But has anyone replaced the evap canister? Is it easy to do? My guess is it is. In which case a little guidance would be much appreciated if I can do it myself. When I do get a new engine for my jeep that's something else that will have to be done. Mechanic's guess anyway because I have an emissions code on my idiot light and I'm sure the charcoal filter isn't doing any good because it's so old.
