I reset mine with every tank of fuel. Link to comment https://www.fordxr6turbo.com/forum/topic/64351-excessive-fuel-economyfaulty-cat/#findComment-963354 Share on other sites More sharing options...

Did a run down south on the weekend, and is only slowly creeping up again.Are you chugging through fuel, or is it just the reading that's worrying you?
