Has anyone in here swapped out there Spark Plug wires? Im on my 4th Coil in the past week. Had my gaskets replaced & 2 coils at that time, then the next day another went out, & now my fourth. Talked to the technician, & he said theres no oil in the plugs... Going to change this one by myself, but I was running by options with my old man, & he suggested replacing the plug wires. I can only imagine the price at the Stealership & couldnt find any at the Team Ford website. Any help would be cool!

Especially as the LS doesn't have plug wires.

right - no spark plug wires running from a central distribution cap to the spark plugs.
The coils sit on top of the spark plugs, and are triggered by a low voltage signal form the PCM. It's all through a wiring harness.

When I was talking to my old man, he was explaining how when the resistance thru the plug wires went bad that it would over work the coils.. Is there a chance the PCM is messing them up some how? Im just blown away that 4 have gone bad like this.

in the old days of coil and spark plug wires - it was possible for a bad plug/wire to cause a jumpy discard from the coil - and over time degrading the coil's lifespan. it doesn't work that way today since their is no wiring between the coil and plug anymore - however - if you are one of us lucky ones where oil was sneeking past the gaskets and into the plug wells - the shorting of the spark caused by the oil had the same deterioration effect on the coil....
Coils go bad - mostly because of heat - which is heighten by placing them closer to the engine.
I would simply swap all the coils - and get past it. the dealer is $100, the ford distributors are more like $60. If the car is reporting mis-fires - then it is very possible that the clyinder reporting the mis-fire is not the one with the issue.
