So, on cold starts I am getting a slightly rough idle, doesnt feel like a mis-fire, but a slight hesitation. Clears up after about 20 seconds. Old car did it every once in a while when sitting at a light. Maybe need to get it in this week. Last car needed a new HPFP at 2k miles, maybe I need one here too.
