I have a 2008 Chrysler PT Cruiser that gets bad mileage. I have disconnected the battery which seems to reset the computer for few days, which jumps the mileage up 24 MPG. Then it slowly resides downward to about 12-13 MPG at the end of a tank of gas (250-350 miles). The car has only 87,000 miles on it and runs great. I have replaced all MAP and Oxygen sensors, plugs, air filters, etc. {black}:idontknow: which helped a bit but not a whole lot. Any Ideas? Help?

Does anything look weird in the OBD2 live data? do all sensors work properly? and are the replaced sensors Denso/OEM?
The car is "adjusting" it self based on the data from the sensors, so bad data may cause this.
