I had a '01 that would do that coming up to a stop. Under warranty, the throttle body was replaced but it can be cleaned.
Give it a cleaning with the spray. I understand it was common. Since it was replaced, I would about every year if I thought about it, spray some throttle body cleaner in there. I didn't have a problem since then & I drove it for 11 years.
