Can someone let me know how many steps their IAC controller is registering when engine is at Idle?

My IAC is at 22 steps at idle. Was wondering if it should be lower. Thanks

If you have acceptable manifold vacuum and the idle speed is correct it shouldn't matter. What problem are you trying to diagnose in the first place?

Idle too high (1100 rpm), but found problem.... Upper intake gasket leak...
