Yes the spark plugs and coil overs were actually replaced with new. I happen to know the Ford mechanic that did the work. Boy those coil overs are expensive - about $95 each for 10 of them!!!!

Did that include Labor ?

I recently replaced all 10 coils & Plugs on my 2006.
Genuine Motorcraft coils were $ 24.00 each. Amazon Motorcraft Coils for V10

Changing out was a PITA. I now know why Dealers charge between $ 1,000 & $ 1,200.00 to change coils & plugs.

Total cost at my Ford dealer to replace 10 spark plugs and coils, fuel filter, serpentine belt and oil pressure sensor was $1,776.53 back on Feb 2017 at 99,167 miles.

Wow ... so nowadays we have to change several coils ever so often (which I have to hire done for $$$$) ... instead of one coil, one set of distributor points, and maybe a set of spark plug wires ever so often (which I could easily do myself for $).

I guess I understand that???????? [emoticon]

P.S. I'm not interested in hearing any reasons/excuses as to why "individual coils per plug" is some kind of advance in non-diesel fossil fuel engine technology. One can always come up with explanations as to why us common folks should have to spend more money to get by.

I have no idea whether this will work for you, but here in FL many stations have no alcohol fuel, mainly for the marine motors, I have been filing up using this fuel, no
more pinging & better mpg

"My Ford dealer says that as long as I am not getting any check engine codes that my oxygen sensors are still OK and not causing the reduced mpg problem."

Yep, that's what they will tell ya! If there aren't any fault codes, many of the "technicians" of today are literally . . . . . lost.

At 115,000 miles, is your engine using any oil? Say, . . . . more than a quart every 750 miles. If you can't find anything else, it might be worth checking to see if your catalytic converter is getting plugged up. When cold, hit it with your hand and listen for rattles. (broken honeycomb substrate) If no, then removing it and shining a flashlight through it will tell you right away if there is a flow problem. While you are down there, check the entire exhaust system for dents, crimps, etc.

My V10 at 115,000 miles used only about 1 qt oil in 4000 miles.
