Idle speed too high, when in neutral

What is your question?

The idle speed is approx. 2500 RPM when first start, doesn't drop down. Seems to run ok, and RPM' is OK, except when shifting, or in neutral??

There is a high amount of air getting into the engine due to an air intake leak, improper sensor readings sending false data to the engine's processor causing it to call for more air and fuel, or possible a sticking idle air control valve. Testing is required to see what has failed.
