The check engine light is telling you something is wrong with engine control systems, thus poor fuel mileage. Trac off light is telling you something is wrong stability control systems. Two separate systems, but both systems use the diagnostic port for trouble codes now. So have the codes pulled, that will give you a spot to start with diagnosing the trouble.
