The only time my car ever held 12-1400rpms at idle was from an intake leak. When I start my car it will hold at under 2k and then work its way down to under 1000.

Same. My old Z28 had an intake leak (after my father snapped off an intake bolt and decided it would be okay). Since then it had an intermittent high idle.
