Rough idle during warm start

Hi, I have a tiny problem with my car.

When I start it up it idles really low and stalls sometimes.

This only happens during what I think is a warm start. I usually drive to work in the morning, then to lunch, then back home. roughly 3.5 hours in between starts and stops. It never happens then.

However if I'm driving like shopping where I drive for 15 minutes shut off the car and go in the store, then come back out and start the car back up to go to another store, that's when it happens.

It never happens while idling after driving the car until the engines warm, only when I initially start it.

Maybe it's the o2 sensors working under the cpus warm start program and the o2 sensor is not warmed up yet during that warm start or something. Regardless I'm going to change the o2 sensor when I get the chance it's probably got 120,000 miles on it and I already have the replacement sitting in my garage.

But can you guys think of anything else it may be? Anything else I may want to look into.

Edit: no mods on the car.
