It sounds like you have a MAP sensor that is out of range and giving the incorrect signal to the PCM. This will cause poor mileage. When this sensor becomes off a little it will not give a check engine light just poor engine performance.

Here is a diagram to help you get the sensor changed out. Here is what its like on your car (below)

Please let us know what happens.

Cheers, Ken
