07' V10 , 15,000 miles . Too soon to lose a Coilpack ?

Just got back from from 1600 miles round trip, stopped for the last gas and at the bottom of the offramp, it's got a miss in it on Idle in gear and on acceleration from the light.. I didn't feel any...

Yes, for those wondering/speculating, the Ford V10, the 5.4, 4.6 and at least some of the V6's are all "COP" meaning "Coil On Plug." There are as many coils as there are cylinders. No high voltage spark plug or coil wires. Each coil is triggered by a low voltage pulse from the PCM/Powertrain Control Module.
