Another dealer horror story. Yeah, I feel the pain, an oil change at the dealer almost cost me an accident. The mechanic, while checking the air filter, clipped off a piece of the air filter flange and it lodged in the throttle body, holding WOT. Luckily, I was on clear road with no traffic. If it would have happened in traffic or in a parking lot, I would have been classified as one of those old farts that forgot which pedal to push.
I know my way around engines but will let Ford handle the plugs. I've found it's incredibly hard to bs an old bs'er, so they better get it right.
This is one "repair" that can be bluffed for sure since it is hidden in a deep well and covered up with the COP boot.
My suggestion is to just make sure you recheck that the plugs are properly torqued after at least one heat/cool cycle. My next tool to buy is the proper spark plug socket which has a 6" extension built on to it.. Although with some luck I will not face this again for another 80K + miles.
As a FYI, my other vehicles ran 140K plus miles on the original plugs, dealer stated on this one (2006) that the plug tips were worn down to the insulator which caused us to have a random skip/miss at 1500-2500 RPM (one of a couple of issues we had)at a mere 84K miles..
Changing the '05-'07 plugs requires having the Lisle removal tool also which can be had for $70 through Amazon just in case the plug decides to break.
One of the reasons the two piece plugs can break of while removing is from extra plug threads showing in the cylinder. These threads get coated with carbon deposits and removing the plugs requires a lot of patience and some luck to..
