I know this is an old question, but I'm having the exact same issue today. I was wondering how you resolved your issue. I need that part and no one has it anywhere. So frustrating.

I'm taking my 2004 Aviator to dealer tomorrow morning re acceleration hesitation problems that cause the suv to shake violently and not accelerate when I attempt to go over 60 mph. Started happening right after a recent oil change. The mechanics who did the oil change said it's not their fault, ran diagnostics and nothing came up. I know almost nothing about cars and after reading some of the posts, I feel like I'm in big trouble. Already had the heads and coils replaced by the previous owner. Any suggestions I can tell mechanics tomorrow?

I suspect bad coil packs.There is one for each spark plug.There
have been service bulletins on them.The warranty on them
was extended through 100,000 miles.There have been some issues
with the #6 & 7 cylinders.My engine was eventually replaced.
Here's to hoping it's just the coil packs.Good luck!

I thought the 4.6L still used a single coil pack rather then COPs. Either way it does sound like a coil problem but could also be a clogged fuel filter or fuel pump.

I believe the engine was redesigned to address the overheating
in the 6 & 7 cylinders.Perhaps the coil configuration was changed
as well? I agree that it could fuel related but this has happened
to me with 6 coils.My has had the same problem with 4 coils
on her 5.4l expedition.

Abtrman and akirby- you were right on- coils and clogged fuel injector- you guys are awesome! The cost to replace some coils (and some spark plugs) and flush the system came out to $1,100 which I can afford. Can't wait to get my baby back purrin like a kitten. Thanks; I was relieved to hear it from the mechanic today because u gave me a heads up. Thank you again for the fast responses and you were dead on target.
