My vehicle stalls when idling it idles rough and stalls frequently. The service engine lights been on and I've replaced the erg vacuum regulator and idle temperature valve. Those are the codes that came up when I had the codes read. I had a mechanic check it out and he found no leaked or anything wrong when he did a diagnostic and said it was fine. I picked it up from the shop and it stalled after about ten minutes of driving when I was still.

Have you checked for vacuum leaks and the IAC? (idle air control valve)

There are no leaks and I replaced the idle air control valve. The engine light came back on for the erg vacuum regulator I've already replaced.

When you replaced the EGR, did you clean all the carbon from the intake?
