just to throw in an update. the stuttering under load and going uphill is gone. still have something going on with it sputtering while reving at idle. i might have to change the fuel filter. but the coil pack helped my fuel mileage come back too

Because you get what you pay for. Cheap aftermarket coil packs have a higher failure rate then Motorcraft coil packs.

Default possible coil problem

I have found the problem to occur both under load and worse if it's very wet or foggy out. It also seems to occur when the car gets hot, this really leads me to believe that it's one of the coils... these symptoms are very indicative of an electric problem. I have ordered 8 coils from american muscle on the web for a really great price 269.95 done and out the door...the brand is accel super coil they are yellow with black boot. I really think that is the problem will let you all know soon, 4 days from now 12/03/2012 wed.

Thanks for the thread guys I have had the same problem and just went and got the coil pack from Advance Auto and so far I am satisfied that was the problem. if it starts haunting me again I will let you know as this is a problem that comes and goes so time will tell all.
Thanks again

Ditto. I've been having trouble with my '05 V6 since Thursday (which uses a similar coil pack). Had already ordered a replacement pack earlier this evening, but sort of comforting to hear the identical symptoms being caused by coil packs going south.

Eh? What has a tuneup got to do with a coil pack failure?

In my case, the car had a "tuneup" less than a month ago (fresh plugs, wires, cleaned TB, MAF, Air Filter, new fuel filter)

Not to scare you but if it does come back it could be the new coil again as well. Try to get at least Motorcraft or better. The "OEM replacements" from parts stores are known to be pretty sketchy. So don't go throwing money at other parts and get frustrated thinking at cant be the coil cause its new.
