96 XR7 55,000 miles V6

Have the original spark plugs, in the engine. Ford says to change at 100,000 miles. Local mechanics say 60-70K miles.
I have noticed a 10% drop in MPG. Used to get 31 MPG, now 28 MPG on long trips. Anyone in the NYC area help me change the plugs? I don't have the tools necessary to do the job.
Car has been maintained properly, the car is all stock.

That 100K plug stuff is garbage. All my Fords have needed them around the 30K mark. Hope you find some help, its not that bad of a job, just looks harder than it is.

How the car run at idle? Could be something else too, like the fuel filter. Those are really easy to replace and I do mine every year and 1/2 or so..

Good call, Thomas on the fuel filter. Very easy job to do.

Laminarflow, I live nowhere near New York, but I would like to encourage you by saying that changing plugs really isn't too hard on our 3.8s. As for the tools, you should need only: 1 deep spark plug socket, a ratchet, and an extension. I think you will need either A. a wobble-bar extension or B. a flex-head ratchet and a regular straight extension. Oh, and some silicone di-electric grease and anti-seize compound. (They come together in a 2-pack called a "tune-up kit" at Advance.)

So, I don't know if you can borrow those tools, but if you can, it should take less than an hour. Things can always go wrong, but it's unlikely here.

A swivel would probably come in handy but I've never used it. I've got plugs down to a science and can do them in about 30 minutes. plug socket, 3/8 wrench and short extension.
