Is it possible for a carbon arrow that has hit the ground after missing not to fly correctly? it seems if i take a new arrow out of the bow i shoot good with it but if i miss the target a  few times it doesnt shoot like it should and flies left, any way to check this or see whats going on?

Arrow, not really. Unless they got a big hit and the shaft cracked at the nock - it happens sometimes if you hit metal ...
But again, I think is related to how you see you as archer.
"but if I miss the target few times' is the real culprit in my opinion. You lose confidence and start to adjust things that are not the problem.
