The factory wires don't last very much in the hot environment. I'd
recommend replacing them with a set of 8mm wires and be done with the
problems.

It is possible that the first and the second plugs were cracked upon
installation. Over time, the crack will worsen and failure will occur.

Subject: DML: Spark Plug Failures? 3.9L V6
I own a '00 Dodge Dakota Quad Cab. It has the 3.9L V6
with the 4 speed auto.
Dec 2002, at 64k miles I had the engine tuned up.
Within 4K miles, the engine ran rough at cold startup
and developed a severe miss and the Engine Failure
light lit off. I took it back and the trouble code was
a "Misfire detected in cylinder #2". The mechanic
determined it to be a cracked insulator on cylinder #2
spark plug and replaced the spark plug under warranty.
4K miles later, the engine started running rough at
cold startup, had the same miss and the engine light
lit off again. The trouble code was again "misfire in
cylinder #2". Pulling the spark plug, it was found to
be a cracked insulator once again. It was replaced
once again under warranty. The mechanic could offer no explanation for a
double failure of this type.
I have to believe the odds against 2 defective spark
plugs winding up in the same cylinder on the same
engine failing in the same mileage are astronomical.
All routine scheduled maintenance has been performed
on this truck.
Has anyone else run into circumstances as I've
described or have any ideas what could be causing a
failure of this type?
