You should change all the injectors at the same time. Now you have one new one while the rest of them have 14 years of wear on them.

.
The problem with the headlights is a common one and it is in the low beam relay.; In the under hood fuse panel, locate the HDM relay, swap this relay with the FAN relay next to it. If the lights stay on, replace the relay. This is a solid state relay, so make sure to get the same part number.

Ihat a Dealer could do. would go back to rebuilder. This sounds like Electronic controls are not regulating base warm rpm. There is usually a slight adjustment in the "throttle position sensor" which has a slotted side and a stationary pivot point. You won't get much, maybe 50 to 75 rpm but if both attaching bolts are loosened and the TPS is moved along the slotted end, it may be enough to help.

There are some electronic adjustments or even a re-flash to factory specs that a Dealer can do. Really do not want to bring bad news, but Phasars for camshafts are fed by oil journals which make Phasars work. If passages are not equally clean, then Phasars will adjust differently on each cylinder bank. Higher rpm means higher oil pressure

I don't know where that wire goes, but the driving lights are only supposed to come on when the headlights are also on.

Yeah so bank 2 is the drivers side and 5678 are on that side you posted this in ford so it's either a 5.8 Windsor motor or a 5.4 and the camshaft sensor is on the timing cover under the valve cover about 2 inches or so go to rockauto.Com and look up your vehicle and the parts described here then you can see it before you buy it

This is a little tricky because they are tamper proof and what seems to have happened is that it has locked up on you , you can try to pull suddenly on it to see if it will free itself ( but my guess is you have tried that already but if you haven't you need to pull it in a fast jerking motion and release your grip immediately to give the belt a chance to retract ! or you could try using a hair dryer on the hot setting to heat the mechanism up and then try the quick pull and release method ! lastly some lubricating spray (WD40 )using a long directional spray nozzle to help free it up .

May have a wire rubbing somewhere ... check under the truck ... oxygen sensor wires ... if not running or on the exhaust ... see if you don't have wire rubbing on the drive shafts somewhere.

It's probably the FPDM - fuel pump driver module . The fuel pump is controlled by pulse width modulation by a electronic control module .electronic Returnless fuel system . The fuel rail pressure sensor is a input to the PCM - engine computer , when low fuel pressure the PCM sends a command to the FPDM to turn the fuel pump on longer . This part FPDM has known high failure rate on F-150 of your year . Because of location it corrodes an shorts out inside .
