94 Civic DX gas mileage drops 30% below freezing
Why would gas mileage drop from 38 mpg to 27 mpg when the day time temps are in the 20's? New distributor and cap, ACCEL wires, bosch4 iridium fusion plugs. Never had a prob with the fuel injection. New fluid in the Transmission. Mobile One extended protection oil.

I would think that the drop in mileage is due to a rich condition. In the cold, your choke may not be operation correctly. Try spraying some carb cleaner into your throttlebody.
