You might be better off posting in the forum pertaining to your truck.

The Garage and Workshop forum is for discussing tools, work space, and similar issues. I have moved your thread to the 2004-2008 forum, since in your profile the listed truck is an 06 F150.
How is the truck running, and which engine does it have?

174 and 171 are normally vacuum leaks letting excess air into the intake manifold.. common problems are cracked or broken vacuum hoses. If you have the 4.2 V6, some have intake gasket leaks...........

345 , 349 cam position sensors make me think of the 5.4 phaser and timing chain problems... do you have excessive noise or rattle inside the motor ? Is it a 5.4 "
