cam sensor

i noticed i only had 1 screw on the cam sensor and the other wasnt there. big deal? seems loose, what should i do?

where would i find a screw for it, and how do i put it in? the furthest back screw, under the snout

Take the other one and go to your local hardware store, I bet you can find a screw for it there if not try the WANT TO BUY area here, lots of luck with my part searching.
