just bought a 2004 f-150 FX4 and it has some serious electrical issues. the digital mileage display will go blank and the shifter brake release switch will go dead causing me to have to pull up the cover and hit the bipass button. also sometimes when i put it in 4x4 it wont switch back to 2h. if i disconnect the positive battery terminal it will reset all 3 and could be good for a few days then goes back to the same. also i am having issues with it stalling out if it idles for to long. hooked up obd2 and am getting running lean bank one and 2 codes.
