I'm from NJ, born and raised and been back and forth 4 times for visits over the past 14 years. Also to answer some more questions, the oil was fresh when I purchased it and I had it changed to Mobil One 5w-30 April 4th and have maybe put 500 miles since then. Also at the time of the oil change I had them replace the air filter. I'm not sure of the last tune-up of the car but the plugs, when I pulled them were clean and the electrodes had no visible wear. The wires, OEM, were clean with no visible breaks or cracks, and a check with a digital ohm meter showed that each was with in the acceptable tolerances. As for the condition of the fuel filter I had that changed last week just to see if it made a difference and thus far, no. So I'm baffled by it, I'm throwing no codes and the engine and whole car is lickably clean, literally. I'm not leaking any fluid and I also had all the brakes replaced with new rotors and ceramic pads, they aren't dragging. I'ver run some fuel system cleaner through it and I'm about to just say screw it and run some seafoam through it too...(SMOKE), so otherwise I'm clueless.

Sounds like everything is okay... I don't see why your getting such bad gas milage.

Maybe you can disconnect your negative battery cable for like a half hour and then start driving it again. So the PT computer can learn (Again) how you drive. Maybe the person that owned it before you floored it from stops and now the PT knows that your going to floor it and therefore acts like you are flooring it all the time.

Sorry if I am of no help - just trying to help!
