Can anyone give some advise on changing the cop's? Is this basically the same as the plugs in that you need to remove the fuel rail, etc.

 

Have you done a search? Plenty of advice and photos.

 

Nah , you don't have to take it off - I pull the 4 bolts an flop it on top of the manifold and leave the feed and return lines connected.. On the 5.4L you have to take it loose on the drivers side to pull #7 COP - That's the least you can get away with..

Once you get into it you'll see what you have to do - it's not bad .. You can search like Torkum suggests - theres lots of pics on here..
