Coil problems
This is the forth coil I have had to replace.
Four in my 2001 4x4 F150 4.6 and one in my wifes Lincoln
To-day I ran into a large puddle (flooding) and it started from there. I recognize the symtoms of a shot coil. It seems moisture is a result everytime.
Macahanic tells me its a poor design on the seal of the boot.
Any ideas. I have all of them is there a way to test them.
Cheers
Michael

You need to replace your boots on the rest of the coils. They are the cause of your problems. When they get old they crack & allow the spark to short out to the head.Use plenty of dielectric grease on them too

Today on my way to school my 02 5.4 started missfiring on #4 cylinder, im wondering if I have the same problem. We just got 18 inches of snow and I have been going through it up to my doors for three days in a row. I was thinking it may be a coil and it is highly likely that it got wet from the snow, does this make sense.
