Whats up guys, hey so I'm driving home today and the sevice engine soon light comes on. I check the code and its a PO4055 Evap System Large LEak. and the possible things could be either the fuel cap, vaccum leak, the canister is not working or broken or not plugged in, or the purge valve went bad. Any ideas of where to start looking and where is the canister and the purge valve located. Thanks
