Anyone have ideas where to start diagnosing the cause of low mileage? I'm getting well under 20 mpg with a 94 Taurus 3.0 wagon that runs fine, idles beautifully, starts every time, and drives straight and true.
60% in-town, 40% 65 mph highway driving.-- EEC-IV code reader returns 1-1-1 (no problems)
-- D"O" is selected on the AT, and overdrive is definitely working
-- Moderate driver, no accelerator punching -- ok, not often, anyway
-- Regular gas, no pinging and no mpg change if I go to higher grades
-- Tires at recommnded inflation (Goodyear Aquatread -- but mileage sucked before putting them on)
-- AT AXOD-E has usual '94 troubles (when warm, occasional slam shift at slow down followed immediately by speed-up -- such as a Yield sign or a turnpike tool booth -- and occasional shudder)
-- No obvious gas leaks at tank or engine and no raw gas smell
-- Litte or no chance that gas is being siphoned by local teen-age Moped riders
Any ideas where to look?
