Default RPMs go up high on neutral when car is running

My 02 ss started idling high after my second pass at the track yesterday. If I put the car on neutral while it is running the RPMs will go up to 3500 bit will go down after I'm at a complete stop. Vacum hoes leak?

Running airflow in the tune is my guess.
