What would cause this code 2005 F150 runs but rough

Question

Engine light came on pulled p0002 code

Answer 1

This code is for high fuel pressure rail which you do not have, What code that you would set and would make the engine with a rough idle would be P0020, this is the camshaft intake position actuator, / open Bank 2. this would cause rough idle going from a cruise to a slow down or stop. If you have this code which almost every Ford  will have sooner or later replace the camshaft actuator solenoid.  as soon as possible. it only gets worse.
