Re: 2004 misfire
Coil c is cylinder 3. A is 1, B is 2, and so on. Are all the coils and plugs new? Did you use quality parts? Like Motorcraft or Autolite? Ford does not like cheaper ignition parts.

Re: 2004 misfire
I hate to say it, but to really diagnose it, it needs to be put on a scan tool with graphing capability. have you thought about maybe a partially clogged injector also? Problem is, there is just guessing going on. Are there any other codes? If the EGR were at fault the LTFT and STFT would be off.

Re: 2004 misfire
where are the LTFT and STFT numbers supposed to be?
(I realize this thread is a little old, none the less, I have hope)

Re: 2004 misfire
The fuel trims should be close to 0%. They both range from +/-25%. Usually, it's acceptable to be within +/-10%.
