IAC Error

[dready]

Hi, my Smartcraft is showing Engine Operating with reduced Power, IAC Error.
Looking into the Fault it shows Port IAC Error.
However, Both engines Idle just fine. would this be just the sensor failure and not the IAC valve itself?
Thanks.

When my IACs went bad, the engines still idled fine, just at a lower RPM than usual. I would recommend replacing the IAC and whatever you do, DO NOT switch IACs from engine to engine. Bad things can and do happen to your ECM when you do that.

That's exactly what's happening. Thanks, I'll give it a try.
