Thank you for the info. I have tried plugs maf and tb also the fuel pressure test good. I have been a tech for 9 years I worked for toyota for 7 and now with honda. I dont have vary much ford experince. This system is similar to the toyota. When unpluging the cam sensors it does run better when hot but it doesnt tell me if its the phaser or the solenoid it just tell me it is something to do with the vct. I can see the the phaser and it is not buldged or damage from what i can see. when the truck stalls and its hard to start Its like the timing is off but I'm not sure is the phaser wont reture or if the solenoid is holding pressure or if there may be a blockage somewhere. It only get like this after I drive it kinda hard. I'm thinking the phaser is maxing out and geting stuck for some reasson. Also it has a bad rattle knock when its messing up under 1200rpms when i rasie it over 1200 it runs smoth and is quiet. From what i can tell oil pressure is good and the truck runs great at highway sppeds as long as rpm stay over 1200. Thank you
