[QUOTE="Falcon, post: 93323, member: 84"] One problem I have experienced several times on my 01 5.4L with 140,000 miles is plugs shorting out. No. 6 is laying down now. I have a buddy who is a great mechanic, and he said it was the coil pack shorting down the ceramic to the block... once it started by water getting past the boot, it makes an arc trail and it continues to short out even when dry until you change the boot and or plug. Does that make sense to you, and are there any problems remaining from that issue? Falcon [/QUOTE]
