When i turn on the car and let it warm up it idles at 2k. there sre two vacuum hoses that go into my intake from below the throttle body, the smaller of the two, if i disconnect it from the intake and plug it the idle drops to 900. What might that mean?
Edit: sorry for the lack of info lol just trying to explain the unexplicable

Idle is controlled by airflow. Find your air leak.
