F150online Forums - 2005 F150 Fx4 hesitating

So my truck started running a little funny with the check engine light blinking every once in a while so when I started really pushing on the gas to try to get the check engine light to stay on so I could scan it, it was vibrating a lot and hesitating to go. The scanner said cam sensor but would that be the only thing causing it??? And does anyone know how to even replace the can sensor??! Also last note when I pulled up my driveway from when I got the check engine light to stay on, the truck actually started to idle so low that it just died. Figured it would've been a fuel pump issue or F/A ratio problem but nothing else came up on the scanner.. Any thoughts?? Thanks!
