Ignition Coil Replacement
I have a 99 Expedition 5.4 engine. I am attempting to replace the second ignition coil from the front on the right side of the engine. I cannot get it to seat whatsoever.
I uninstalled the front coil and placed the new coil there and it seats without an issue. So I tried to seat the older coil in the second position, and it will also not seat.
I have lubricated the coil, with no success.
Any suggestions?
Thanks in advance.

Broken plug
I did see what I think now is indeed the top of a spark plug, which is restricting the seating of the ignition coil.
Seems I should take it in and have all eight changed. I am not sure how difficult it is to change the plugs on this vehicle. I will look and see what is involved and call around to see what that may cost.
Thank you for suggesting that possibility.

You will find most shops will charge you around 200 bucks in labor to change them out. It is a pain to get to the back two plugs on each side but with several extensions, remove the engine plastics, some twine to pull your heater hoses back, and some patience, it can be done in a couple of hours.
The good thing is you don't have 2 piece plugs to break apart. Use anti-seize on the plug threads and dielectric grease on the coil packs.

You must've got real lucky with a repair shop around you. Most places charge $600-$700 to replace the spark plugs. They also charge $20 per spark plug making just the materials $160.

Final Tally
Picked up the Expedition this am.
They used a cylinder head repair kit on the cylinder where the plug blew out. So this cylinder now has a longer plug, and a shorter ignition coil installed.
They went ahead and changed the rest of the plugs and ignition coils, as well as replaced the PCV hose assembly, which I knew was showing it's age.
Final cost with labor: $549.
Thanks for the responses and advice. I am glad to have found a great shop, which was recommended by a friend.

and I'm in So Cal where nothing comes cheap! Most use the standard Chilton labor guidelines and charge that job times their hourly rate. 549 for the plug removal and new plugs plus labor seems reasonable.

It's in the ball park. $200 is not.

So why did you mislead him up in post #6 by saying, "You will find most shops will charge you around 200 bucks in labor to change them out"?

Mislead????
Did you read his complete message???
"They used a cylinder head repair kit on the cylinder where the plug blew out"
Did you think this was free???
The 200 bucks didn't include having to do the ADDITIONAL work as noted.
Mislead??? Come on!
Do your homework first please.
