Answer 1
2007 4.7L camshaft position sensors failures are not that common. More common that not is a Dirty throttle body. Contaminates from combustion gases leave a residue on the throttle plate and bore called "coking". This condition will restrict air flow through the throttle body when the throttle is closed, as being at a stop light. Common symptoms are stalling on decel (foot off gas), hard starting, stalling at stops. This seems to fit your concern -

so what do you do? My 07 4.7L has started stutter start when I turn it on. It turns on, but he light flicker and it makes this weird noise like it is trying to crank a couple of times and then it kicks on? Could this be the same thing? -
