I guess if the transmission does not disengage it will kill the engine coming to a stop.

When I come to a stop yes. I'm gonna replace MAF sensor and CCV valve.
My car doesn't have disa or icv I think.

Fix

What was the fix?

Upped drive position idle speed with dis

I don't think you've actually fixed the problem -- though the symptom may be gone for now.

I think it's maybe the throttle body or the faulty regulator yeah but like that it's perfect

I am havng the same issue and just loaded DIS on my PC. Can you tell me where to go in the software to make these changes?

Diagnostic, function selection if I remember, complete vehicle menu, then engine electronic or DME no need to select further submenu, and then click on test plan.
