EFILIVE help v.retarded high idle

i have no idea whats goin on here, its idleing at like 2400 and wont go down. IAC steps are at 0 at idle. The car has a 224 cam, headers/ypipe/catback, ls6 intake, slp lid/kn filter. Ive replaced the IAC already and no change.

Intake leak of some sort, the PCM is commanding zero airflow (0 IAC counts), yet the motor is still running at 2400 RPM.

Intake gaskets, or PCV system are the usual suspects.
