Miss at idle when cold

[BOP4ever]

I have noticing on cold mornings my GN has a miss when I first crank it up.
I think it goes away after it warms up a little. Car runs fine otherwise just wondering if this is normal.
Thanks

How old is the coilpack/ignition module? What plugs are you running? Gap? What kind of wires?

AC42 plugs. GM wires, unknown age on other stuff
Car runs good otherwise .
