Any Ideas P0442?
I have this code P0442 Subaru - Evaporative Emission Control ( small leak ) on my 2003 Wrx wagon.
My friend looked at the fuel pump seal , small hoses at the rear charcoal canister changed the cracked ones , looked at the fuel filler cap ( seems good changed 2 years ago, and I don't smell gas ) also changed some hoses near the front alternator ( around the blue T- fitting ) but I still get this code after I clear it.Comes back on by end of the day maybe driving home from work.
Please any ideas how to find this cause ? this is driving me confused .

If it is your emissions system going bad, I wouldn't worry about it too much. I drove around with everything capped off and the purge valve removed. Mine was leaking from the T section and I so happened to break a nipple of the valve.

Actually, come to think of it, have you noticed any fuel smell from the vehicle under the intake manifold? There was a tsb in regards to bugeye with an updated fuel line kit that replaced the fuel line under the manifold and a bunch of hoses that connect to the fuel rail.
