whats the firing order on my ford expedition 5.4L V8

No,not at all.It is a tight squeeze,but I do them all of the time.What makes ot easier is getting a bungee cord and wrapping it around the heater hoses and hook it to the right side hood shock to give a little more room.Use a 4 inch extension with the spark plug socket on the end of it,and a universal joint and then a long extension attached to the other end of the swivel.Hope this helps.Be very careful not to strip the threads also.
