Greetings all, I am new here and know next to nothing about cars so any help would be greatly appreciated. I have a 97 chevy camaro rs 3.8L, V6. My engine light came on and and after taking it to Autozone I got an error code that I have a misfire on cylinder 6. Since then it has started to over heat. It hasn't hit the red line yet but is getting close. It idles very rough and feels like it is running rough as well.

What do I do? What should I have replaced or fixed? PLEASE HELP!!!
