Spark plug change

[ViperRob]

I am trying to change my plugs. Got them all changed except 4 & 8. 4 is misfiring and needs to be changed.

How can I get to them without having to take it to a shop?

And are you sure its the plug? I would have went on Amazon and ordered a set of coils for 65 bucks. Ignition Coil Ford Excursion Expedition Explorer V8 4.6L 5.4L DG508 Pack of 8 would have saved you the heart ache of going back and cussing it out again
