I'll start from the beginning
The truck was taken to ford because it barely ran, the told him a cam locked up.He brought the motor to me for a rebuild(ford left the valve cover off and there was dirt all over the head so we couldn't start the truck to diagnose ourselves)
We pulled the motor, found no real damage other than oil not changed enough
and rebuilt the motor(rings,bearings etc...) When the motor was first cranked
it ran real rough so we pulled the timing solenoid from driver side and one of the screens had been pushed in and the plunger wouldn't work. The engine then ran pretty good but went back to running rough within a week. We the found the motor on the intake that controls the flaps in the intake runners stopped opening flaps. We replaced that but now it still runs rough. We thought the motor may had been timed wrong so everything was pulled back down and retimed again but still runs rough.
We have replaced the other timing solenoid and cam phaser and I'll now tomorrow if that helped
