Have Ford Questions? Ask a Mechanic for Answers ASAP
I checked alldata and they show tests(too much to list) for the coil over plug, the wire harness for the coil and the pcm(driver circuit). The symptoms you described go with my experience of a bad coil. I would power balance with the scanner, the misfire would show up under load. They also said to check the spark plug gap on the cylinder that is misfiring. Not uncommon on these engines to have several coils fail or even one after another in short time periods.
Good Luck Mike

I am jumping between two computers in the shop that are shared. Ignition coil D is cylinder #4. I have more information now written down if you need more. I would try the coil.
How did it work out?
