Taurus V6-182 3.0L FF (1995)
DTC 416 Indicates the IAC adaptive learning has reached the maximum learning limit (the valve is admitting as much air flow as possible).
NOTE: Idle speed surging commonly results when the IAC solenoid reaches the limits of its operation. The IAC solenoid cannot compensate for
the required change in idle speed which results in the engine surging between the upper and lower limits of the IAC system.
