I would start with the cheapest things first.

1) Check or replace the thermostat and PCV valve.
2)Try coasting down a hill that you know how fast your older Metro sped up. Maybe you have a bad wheel bearing or brake pad/shoe dragging.
3)Try cleaning the injectors.

Just a few ideas, maybe other folks here know of more reasons for bad FE.

Another issue I have had lately is the Ethanol in the fuel. Sometimes it drops my FE by 25%!! And the number of gas stations that sell pure gasoline is decreasing every month.

I suspect the oil companies are adding more than 10% ethanol in the fuel. Who knows? I really don't trust Mobil/Exxon to tell us the truth.
