How long have the spark plugs been in the car?
Maybe, just regap the plugs to spec (check the sticker on the inside of the hood; it might read something like 1mm 0, -0.1mm tolerance which means gap them at 0.9mm).
If the plugs are worn out, replace them (gap them to spec per hood sticker).
Be careful about torquing the plugs the treads in the head are aluminum. (the torque spec is pretty low)
It may sound stupid. But, check all the engine grounds and the car body ground for good connection. Also, a weak battery can cause all kinds of bogus problems.

This, along with a scangauge and GPS for accurate odometer and speed readings, and the associated change in driving habits, have gotten averages as high as 50 MPG on a long highway-only trip at night last summer , but my commute and other driving have led to an average of 42 MPG over the last year.
