i got a code for cylinder 4 misfire, which one is that, on my mustang they arent in a row and i dont know alot about gm engines so dont know if they are labeled or what. thanks

The fourth cylinder is the one all the way to the right closest to the drivers side. Starting from the left or passenger side they go in order, "Left is 1-2-3-4 is Right" The firing order is 1-3-4-2. If you need a chart .. http://autorepair.about.com/library/firing_orders/bl-fo-4203.htm
Good Luck
