Hi there,
Based on the details described, the rough idling and stalling problem when the AC is on and when turning could indicate several ongoing issues:
1. A bad idle control valve. If this part is bad or dirty, it will not adjust to the proper airflow when the AC is on, resulting in a rough idle.
2. A failing AC compressor. A bad compressor can increase the load on the engine, especially at idle. It will cause the engine to struggle, which will cause stalling and rough idle.
3. Vacuum leaks. Leaks in the intake system allow unmetered air to enter the engine, disrupting the air-fuel mixture, which causes rough idle, stalling, and low engine power.
4. A dirty throttle body. If in bad condition, it leads to rough idle and stalling issues.
I hope this helps!
