Hello and welcome to just answer. Excessive fuel consumption can be caused by a failing MAP sensor, coolant sensor, Oxygen sensor, sticking fuel injector, excessive fuel injector(s) or a stuck open evaporative emission purge solenoid. Have you had the Jeep scanned for any diagnostic trouble codes yet?
