I slow down to turn or stop it stalls out?

Hello,

This sounds like an issue with the idle air control valve.
If you have dirt and debris build up inside the valve, it will have restricted air flow internally and that can trigger rough idle or even stalls depending on how clogged it might.
That valve ca be serviced by cleaning it out.
The idle air control valve is located on the throttle body (see diagram below).
Here are couple of helpful articles:

It will also be a good idea to clean out the throttle body. As a dirty throttle body does affect the way the engine performs.

I attached diagrams for your reference.

Please let me know of any questions.
Thank you.
