Have been having exact same problem. Told it's two coils and codes are 07/M07 and 07/N09. Unfortunately the warranty expired at 10 years or 100K miles. Unreal that I missed this. I received no notice about it and am connected to Ford owner site since I purchased car for notifications....nothing was or is on there. Purchased car August 2012. I called them about it. They said they would place a note in about it and if enough people call them they may extend it further. Call 800-392-3673 (FORD) make sure you have VIN and mileage to give them. They also said if anyone has already paid for it and they extend it (KEEP RECEIPTS) and you will likely be reimbursed.

My 2003 T-bird has had a few instances of hesitation when accelerating. It feels as if the car has died but it's still running. Within a few seconds the accelerator starts working again. That has happened about 6 times in 3 weeks. I took it in and 'of course' it didn't happen when they drove it. Today it happened again. Then about an hour later my check engine light came on. I had never seen that light before. I pulled over, read my manual (don't remember if it was flashing or not). i turned my car back on and it drove normally...no light on. It's been over 100 degrees here the past 10 days so the A/C has been cranking. Don't know if that has anything to do with it.

My T-Bird started misfiring at about 85,000 miles. Took it to Ford Dealer and they replaced a couple of coils. Problem continued. After multiple visits to the dealership over a period of two months and 7 out of 8 coils replaced the problem was repaired. They also told me that they replaced a seal on my wiper motor somehow water was getting to the plugs. (Not sure what that has to do with it.) At 105,000 I took my T-Bird through a car wash and the problem came back. I have had sparatic instances with the engine missing again especially during accelleration on hills. I will be headed back to the Ford Dealership to have it looked at again, unfortunately the 100,000 mile warranty extension for this issue has expired.

The had been sitting for quite some time so we had to jump start it but once the motor was running the idle was very rough and the check engine light came on when we attempted to give gas, without any result.
Had the car towed to Ford by AAA where they charged 2x150$ in diagnostic before they found a bad ignition coil (despite my describing the issue precisely when the car was taken in) and said it would cost 208$ to replace. I did my research on here and found trace of the warranty which I told Ford about...the service advisor didn't know about it. At the end of the day they had to change 4 ignition coils on the car but they were all covered by the extended warranty, as was the second round of diagnostic. Be SURE to bring the warranty up if you car is within the 100,000 miles and 10 years, Ford certainly didn't. Had I not brought it up I would have payed over 1000$ for the work to be done.

ignition coil falure
Visitor, 2004 Ford Thunderbird, 86,000 mi
Had two ignition coils replaced in 2006, car kept in garage. This was before warranty. In May 2010 I moved and started keeping car outdoors. By June the car would stall on acceleration and go into limp mode on the freeway while merging into traffic. I would stop, turn off engine and the car would run normally again (sometimes in the middle of the lane). This continued and each time I returned to dealer, a coil was bad. I've currently replaced all 8 and problem continues. Limp Mode upon acceleration and then engine light stays on. No satisfaction from Ford.
