Why are you using 93 octane? Have a tune or some other reason? Unless you have modified your car with a tune going with a higher grade fuel us just wasting money.

What numbers are you using to figure fuel economy?

Usually when I see numbers this low, someone is filling up, and using gas tank capacity- 14 gal- to divide and figure fuel economy. The proper method is to fill up, hit the trip odo, then when you fill up again, divide the mileage on the trip odo by the number of gallons displayed on the gas pump.

Nearly every Focus we've asked about shows E (light comes on) when the tank has used about 10 gals leaving approximately 4 gals in reserve.

I am going to guess that for some reason the engine is never moving to closed-loop operation. Drive it a while and get it nice and hot then take it to an auto parts store and have them scan it and look at all the sensor readouts and see if the engine is in closed-loop. If any of them look strange, then you may have a bad sensor.

The factory coil is going to be superior to any aftermarket coil. Get a factory coil from a wrecker and I'd bet the ilde miss goes away.
