Black smoke i had that problem before, your fuel lines and fuel injectors could be full of crap/rust that's what was wrong with my car it also was sitting for a while too, if your burning up gas like crazy it's probably your O2 sencer is full of crap, other then that you can check your Intake that also could be full of crap, if it's something more i would go to the Subaru dealer and have it tested
