Hi Guys, I am new to this forum so please bear with me as this will make you scratch your head.

I have a 2005 Mustang GT with 97,000 miles that has a severe misfire misfire when the engine is cold and only when it is cold. As soon as it gets to operating temperature from driving, the misfire disappears (as if the cylinder "turns" back on) and runs/drives like a dream (most of the time its when I hold the RPM at around 3.5-4k the cylinder with come alive). The misfire is on cylinder #1...
