Looked at several vids and help forums but none mention removing the high pressure fuel rail that is above and blocking the ignition coils. Can someone point me to some help on this. It looks like it's beyond my paygrade to do a simple plug replacement on this 2001 4.6 liter with 72k miles. It's running rough sometimes and I don't know the service history although It was very well maintained by previous owner. I do have the stuff to test the coils and firing. Just cannot see how to remove the plugs due to the long rail blocking them.
