Ok i have a 95 gt and the top alternator bolt was missing when i bought the car can that cause my belt to be lose and the car start start up funny like it hesatates to start

 

it could make the belt be loose which could mean the alt isnt spinning like it should etc.. but you would hear alot of belt sqeewk if it was that. Just replace the bolt tighten the belt and see if it gets better.

Also why is weird to start up?

 

buy the bolt...

I don't understand what the problem is
