RE: Sparkplug removal - fuel rails?
also you may have problems with your extension coming off leaving your plug and socket in the hole... I put a small piece of tape on the end of the extension before putting it in the socket just to make a tighter fit.. this helps me.. I'm sure there are better ideas to help with this though...
Taking the intake from the throttle body also will also help.. and I usually have to use a wobble joint and extension on the rear plug on the passenger side (#4)

I like using a "WOBBLE" extension, it allows almost 15 degrees of misalignment, makes getting the plugs out easy. I too find no trouble changing plugs on a mustang. But a 5.4 liter '99 Expedition with rear heat/AC, That's another beast entirely, and a real BITCH on the right rear plugs!

Lightning was a BEOTCH until I got my routine down....I am now at an average of 55 minutes on the Lightning. Record is 34 or 24 minutes...One of those

RE: Sparkplug removal - fuel rails?
More great suggestions, thanks lads - looks like I have a good reason to get myself a set of wobble extensions now yipee!
99BlackPonyGT - I am going to let someone with (more) engine rebuilding experience answer this one for sure so bump.
IMO I would leave them alone, if they are overtorqued then loosening them and then torquing them to the correct torque (11-13 fp) might not work as loosening them may tear the threads in the head. In other words the damage may already be done. If you leave them in there and wait until you need to replace them in another 60,000 miles or so (I heard you can get 100,000 on the platinum plugs) and you have the problem then, well at least you had 60,000 miles of use before have to fix/replace the heads. The problem is that if the heads have been damaged by over torqueing then you might be at risk of a plug blow out - this is where the plug is ejected from the sparkplug hole - if you are in the middle of a long journey that would suck ***.
Again, the above is just what I think myself, hopefully someone else will step in and give more a experience based answer. Good luck.
