All good! Maybe someone else has a similar problem down the road, would make it easier to find w/ its own thread.

If the bad running happens at a certain temp, it's likely some part of the tune. For example:
-Closed-loop idle control engages but settings are not correct
-Idle target drops and now you're operating in an area of the fuel map that isn't tuned correctly
