    Engine Revs High on startup

    The engine in my C5 Corvette coupe revs high on initial startup and is slow to return to idle. What setting controls how fast the engine returns to idle after the start? I'd like to set it to return a little more quickly.

    Lots of tables... but I'm betting base running airflow is too high
