misfire on 3.0 v6 code is confussing

[ITSWRONGWAY]

my 01 escape with 3.0 v6 has code that comes up as po351. the code list says it is the primary coil ?? my engine has a coil pack on each plug so what am I not understanding here ?? it does not give any one cyl. as a misfire. this only happens when the temp outside gets to around 20 degrees.

Either bad wire or bad pcm seems to be most common if you already swapped coil and plugs.
