it could need a complete tune up or it might need a scan to see if there is any fault codes

Have the local stations in your area switched to 10% ethanol?  I noticed an instant 10% drop in fuel economy of my '08 Dodge Caliber about the same time all the local stations switched to 10% ethanol.  I went from 29-30mpg average down to 26-27.
