retiring mustang. help with economy dd

go with the 4cyl mustang. Replacement parts are cheap, and are readily available and in stock, try that with an import.You basically know all about the cars. And you can still customise it to look tasteful(like a 5.0) try THAT with an import!
please. a 2.3 knocks down the same mpg as a 5.0. i drove one for 3 years and it was a big kick in the nutz. dding a 4 banger mustang is a step backwards and has all the driveability flaws that his gt would. not something i would want to drive 120 miles a day.

4 cyl; auto; AC; cd player; power everything. 131000 miles. $950.00. Did I do good? Only thing... service engine soon light on. Suggestions on where to begin?
