mileage just disappearing

well winter gas is upon us here in Ontario and my MPGs have suffered a good kick in the a$*. getting 19mpg now, down from 23mpg (all city). i would not mind if it wasn't for the fact that i did lot of coasting, driving without brakes, no idling (no remote start), and driving with load. just crazy how sensitive my car is to winter gas. it seems to just run so rich now that it's cold and for some reason when i drop to neutral going downhill my rpms climb to ~1300rpm instead of staying at 800. this only happens below 45mph & when Not stopped, and makes coasting in neutral completely pointless.
