I put in a new fuel filter, new 02 sensor, cleaned the MAF and the air filter.
Replaced ALL fluids with synthetic, got a Ultra Gauge so I see exactly when I am using the most gas etc.
The only thing so far that has saved me ANY mpg is switching the ECT button ON, I get about 1 MPG better with it ON.

I have all the parts to do my water pump, timing belt and all belts, thermostat, and going to change spark plugs and wires plus clean the throttle body and replace the PCV valve.
Was going to do that this week but came down with the flu so will have to wait until next week or so.
After that if no change then I give up and accept that I get 12.5 mpg city.
