Replaced the throttle body, TPS, IAVC valve, EGR valve. Now the idle is high and then shuts off. What to test or how to fix?

Good evening.
Do you have any codes set in the system?
Did you do the Idle air control reset procedure?
Roy
1. Turn the ignition switch to the "on" position for five seconds.
2. Turn the ignition switch to the "off" position for ten seconds.
3. Start the engine.
4. Check for the proper idle operation.
Are you sure you have no vacuum leaks?
