Exclamation coil pack problems

I'm having engine problems when driving only. Seems like a severe miss with no power. Think its a coil pack. Problem is on #3 and #7, the coil packs have what looks like a resistor on the end of the spring. Auto parts guys never seen this and I can't buy one from them to replace. I tried putting a coil pack (#7) like whats in the rest of the motor, but when I start the truck it has a noticable miss at idle. Put the old one back, idle is fine but problem is still there. OBM II says misfire on 3 and primary secondary coil failure on "G" Whats G??? Any suggestions?

Right what are you referring to ? They haven't used coil packs since 2001 on the V8 4.6L's. Ford NEVER used coil packs on the 5.4L's and V10's.
