pop the hood, locate the 8 coil packs(they are all black), once you have located each one. Start your truck walk around to each side pressing down on each coil pack one at a time. if your popping/hissing changes tone or stops when you are pressing down on one coil pack, you found your problem.
I had an 04 blow a plug out at work. The fix at the service center wasn't to expensive. i figured it was a pull the head move and rethread the hole. Helicoil repair has held for over a year now.
I'm praying my 5.4 doesn't blow any coils out. Always a risk.
