Off the top of my head, startup airflow, startup friction airflow, idle flare control.

Is the intake air tract, sensor contacts, throttle body ect. all clean and in good working order? If so, then what TAQuickness said.

Most of the time I have seen this it is a mechanical maintenance issue.

Most of the time I have seen this it is a mechanical maintenance issue.nothin behind the throttle body leaks..i have a few ahead of the throttle body but thats not going to cause any problems
