That's terrible gas mileage. I get 27-28 hwy mpg (L32). Something is wrong. Most likely its the MAF, O2, or IAT sensor. could also be a bad plug. I would immediatly do a full scan to see how everything is operating.

Are you making changes to your car, such as changing injector sizes, and not scanning/tuning it?

This is a problem with a built-in solution.
