Cam positioning Sensor Replacement?
04 f150, 5.4 , 4 door (supercrew), fx4. I heard they have alot of them with bad cam positioners I believe its said? Ive also heard that the way of telling is you're fuel mileage goes to hell, and im defintly there, down to 12 mpg?! thats with easy driving (all highways), i have a tonneo cover, everything else is stock, except for K & N cold air intake. Any suggestions, or anyone heard of that? Does replacing spark plugs, or fuel injectors help anything? I mean 12mpg, might as well get a hummer h2
. Let me know if there is anything, or if I should just trade it off. thanks!
Tried using search, but couldnt find anything.
