My 2005 dodge caravan xlt burns to much gas - 2002 Dodge Grand Caravan

You don't say whether the check engine light is on or not so I'll assume it's not. If it isn't the PCM is evidently happy with the way the engine is being controlled. That leaves other things like underinflated tires and driving habits. Vehicles with aluminum wheels have a problem with bead leaks. Accelerating slowly and anticipating stops are important. Drive as though there's a raw egg between your foot and the gas pedal.
