Ford fusion energi 2013 Fuel trims was created by Fadi89
Hello my friends , I am new here , and am not a mechanic , I have Ford fusion energi 2013 , and am facing a drop in fuel mileage and bad acceleration , so I have plugged my bluedriver scan tool , and I have noticed that my LTFT is 10.2%, but it's drop down whenever​ i push the RPM , it's reach around 1.6% when the RPM is 3K , does this means that I have a vacuum leak ? , Also , I have recorded the data from the scan tool for a 30km trip , but unfortunately I can't attach an Excel file here :( , I hope any one can help diagnosis the problem . Thank you brothers

Certainly sounds like one avenue you go down, what engine has it got in It? I know the zetec and duratec lumps used to suffer alot with the rubber hoses stashed neatly under the inlet manifold. Tho I think this may be abit new and have an ecoboost?
