car stalls when engine is hor and not moving

What is your question?

The car will stall when the car engine is warm and it is not moving. This means when I would be stopped in drive or be in neutral.It will not stall while driving. I know it is not the fuel pump for that is working properly. I already changed the computer when the check engine light was on, gas filter and the idle speed. The computer does not have any error codes for I had that also checked.
