I just got my 2.3 efi,automatic transmission, going and I checked my mpg and it was 21 with mostly highway driving. What are some thing I could do to get my mpg up and what should be expected from a 2.3 automatic? Thanks

changing your fluids, new air filter, new fuel filter. cold air intake adds performance and mpgs

first of all, hi neighbor! we arent that far away from eachother. nice to find another fox running around locally.
as for your question, yea, do a tune up on your engine first.
if you feel inclined take off the air conditioning belt, it will get you another 1-2 mpg because it will be removing parasitic power from the system.
you can also delete (remove) the air silencer, and take a few minutes and clean the oxygen sensors. this should be another 1-2 mpg.
driving habits, obviously, play a part. try shifting into neutral at long stoplights to idle, might get you a little more mpg.
it would be a good idea to put your cars specs in your profile, because if you have a convertible rather than a coup or hatch it will affect your mpg as convertibles are heavier, so you wont get as good mileage as the other types. and if your engine only has 4 spark plugs then you wont get quite as good mpg as one of the later engines that have 8 plugs.
fyi, i'm a 2.3 non turbo 8 plug coup automatic a4ld tranny n i'm getting average of 28 mpg.
good luck on your stang
