Why is my 5.4 in my F250 lacking power?
Engine runs great, smooth ride, diagnostic tests produce no codes at all. At
highway speeds trying to pull a hill or pass someone it has NO "get up and go"
at all. RPM's jump up to 4 - 5K in passing gear but no power to pass and very
slow. Does not miss or sputter, just no power. Any suggestions?
