I average 23 mpg wth warmer weather, once the under 30 temps hit in the morning I average around 20.
Definately check the air filter. Probably replace the fuel filter.
I would inspect the convertor as well.
Beyond that, it would seem the engine isn't going into closed loop.

It's stuff to say right now, we need more details.
Is the engine coming up to temp? Do only have the factory gauges or a set of aftermarket as well?
All the sensors play a part in getting the engine into closed and they rely on coolant temp, outside temps and more. And there is a chain of command the ECM relays on with those sensors.
