So recently I've been getting these codes and a CEL at cold startups. Idle starts to get rough and I shut off the engine, then restart and its fine again. Truck drives perfectly fine the rest of the day.

It's not every morning where i'll get the misfires but every few days or so it will happen. My VIN isn't under the recall for a flash of the ECU but I made an appointment next week to have them look at it.

The ones that were under the recall, was it only during cold starts? Or was it continuous?
