What type of ICV (Part #, etc.) is used on the 2015 Buick Verano 2.4L

What is your question?

This problem started without prior warning. Vehicle idles but hesitates or stalls when the accelerator is depressed. Holding the rpm a little higher while applying brakes avoids stalling. I'm pretty sure the ICV is either stuck or bad. I am good with mechanical things. Is this something I can change myself?

What makes this problem better or worse?

How long has your 2015 Buick Verano had this problem?
