Is it an automatic? Any chance it isn't shifting into overdrive?

You have a lot of theories from this board. All require you to spend $$$ to go see the car doctor. It will be worth it.

hi, i just bought teh odb2 code reader and found out that one of the knock sensor as what the reader said(code p0325) was bad. do you think it might be the cause of the bad gas mileage on it? maybe... and also i don't know where i can find that sensor.

Sure.. if the ECM detects knock it will do whatever it can to lower combustion temps, including retarding timing and adding fuel. Running rich would certainly screw your fuel mileage.
