bought this truck new in 2000 original everything, has developed a problem i cant solve. water is appearing on number 4 causing a miss, clean ,blowout ,etc runs again for a awhile and repeats, my mechanic on another 5.4 has seen same issue and has replaced coil boot plug tried silicone on boot , etc nothing has stopped it from occuring again. do not see any leaks in hoses or any moisture at all in area just on boot when you pull it due to miss, anybody experience this?

I remember reading a few links to a heater hose connection that leaks directly into the number 4 coil.... remember a few people having that issue before
