Is your 5.4 stuttering? Throwing codes? How many miles on engine/ plugs?
Codes will telll you which Cop is misfiring.
I have seen some new ratchets that work conventionally and also by twisting the
handle. That might be an idea to consider.
Some people remove/loosen the fuel rail while others don't.
In the old days, it was normal to do a tune-up and change everything out.
I have a V-10 and I didn't change my own, ( I changed #5 and that was enough
for me!) Had a pro change them out for a missfire and it didn't solve the problem.
Found a vacuum leak and that was it.........
Then I had two plugs blow out in 2-3 months!
If I had to do it all over again, I would have changed them myself and used loc-tite
on the plugs instead of never sieze! Idea being that the plug might hold and if it
blows out , you'll need to tap it out to fit an insert with loc-tite and then
a new plug. (kind of eliminating one step)
I don't know if your 99 falls into the plug blowing era, early Triton engines had
short tapped spark plug holes.

On a van everything is cramped in there. I've got the 6.8 which is even tighter. I've averaged a COP one every other year for the past 10 years and they cost about $350 per to replace at the dealer. I finally said enough is enough and bought a full set (10) for only $150 off of e-bay. Held on to them for few months and then finally one failed. I went at it with full gusto only to find out that I could only access one of them with my tools and limited knowledge and capabilities. Mercy was upon me as the one I pulled (front driver side) just happened to be the bad one. No clue how to get the others out when they start going. A OBDII scanner will be purchased then as it's essential to know which one is bad and just concentrate on the missed cylinder.

I found letting the air out of the front tires to lower the front and an extension that locks the plug socket onto it is a great help. Use anti seize and a torque wrench to install and coat inside COP boots liberally with dielectric grease. I did mine (1997 e250 5.4) removed fuel rails and exchanged injectors, motorcraft plugs, and all COPs at same time. The twist lock extension was a valuable tool to have that locks the sparkplug socket on. The padded socket helps prevent breakage to the insulator.

FWIW: I think Ford warns you not to use anti-seize on the plug threads. Not that I am a fan of the 5.4 plugs.
Sears sells a 1/4" drive 7mm swivel socket that some find useful.

It's tough, but with the right common tools, it can be done. I changed on 8 plugs on my 2000 5.4. Last time I changed a COP I couldn't believe I had done it, but I did. I think #1 was the worst. I removed everything that was easy, and loosened up a lot of bolts so that I could 'force' things out of the way.
