How many miles are on your car? I have seen the catalytic converter get restricted, I have seen air flow meter failure, and fuel delivery/ volume problems, but everything is a guess without actually having the car to run tests on. This car has diagnostic capabilities. A computer that has control over the ignition and fuel injection is located in the passenger foot well area and has several modes of diagnostics. Does the car just gradually loose power as you accelerate, or chug and sputter as you try to accelerate?
