My 97 seems to be just as finnicky. Colder temps definitely affect it but sometimes there doesn't seem to be anything to point at. I have an old Civic as my daily so it may sit for 3-5 days not being driven. If I drive it daily the milage seems better and there is no fuel leak. My last tank full was 17 MPG. The one before it 14. Dunno.
