My 2009 Pontiac g8 seems to be having a misfire at least that what the code p0305 mea

When the car is cool started in the morning it does not seem to have a problem up until it warms up and stays idling at like under 1 rpm the car starts to have a shake and the headlights only seem to flicker. when I press on it and the rpms reach 1 and over the shaking and weird flicker stops so I m curious to know what could be causing the misfire at ford vcm 2 only

If you're not getting any sort of mechanical noise related to it, I'd start with the electrical components. Spark plugs and spark plug wires are the easiest to start with. If that doesn't solve your issue, move to the coil packs. To me, what you're describing sounds electrical. There's three things cars need; spark, fuel and air.
