Same thing happened to me when I did the super 6, Mileage suffering but it was running fine. Well apparently I was able to tune it with a huge vacuum leak at the carb and intake manifold, and the egr valve didn't have a gasket, take nothing for granted. Mine now gets 20-22MPG on the hwy if I stay around 65
or you may have a bad sending unit... only if you could be so lucky..Previous owners do strange things but it sounds like the duster is in capable hands now :thumleft:
