i haven't replaced the fuel filter. is that the same thing as the air filter? should i replace both?
what is a MAF?
EDIT: It looks like I may have changed the fuel filter about a year ago. Should I replace it again?
No if the fuel filter was replaced one year ago.
As for your increased fuel consumption. Check all your vacuum hoses for leaks. Vacuum hoses become brittle with time and constant exposure to the engine heat. Then in really cold weather the hose breaks.
