Idle stepper motor OR magic box (ECU) issue



Just took our new to us 2017 Stelvio on a 800 mile weekend trip to the Redwoods.
Noticed a couple times it would die after a cold start in the AM but fine when hot, also had increased popping on downhill runs.
IAC valve or something in the FI / ignition realm?

I think this Bike is the best all around, for me anyway. I can't wait to ride it.
