What would some causes be for a sudden high fuel consumption ??

It just feels like I'm going to the gas station more frequently now, is there any known reasons for higher fuel consumption during colder weathers?

Any other reasons for higher fuel consumption just suddenly?

Bad 02 sensor or you maf is dead.

Unplug the maf and see if the car runs the same. If it does you might want to have someone use a vag on your car and look at block 002 or 003 and see what the maf readings are. You can also look at block 031 and see if the 02 is working right.
