    Welcome Butch.

    Lets see some pics of your truck!

    That woosh of air has nothing to do with your SES light and code. All of our trucks do it, and you can really hear it on the trucks with a CAI. It is the pressure that the SC makes while spinning (even at idle) equalizing with the atmosphere through the throttle body.

    You are likely having the typical leaking turkey pan elbow issue, and if not that then there is a vacuum leak somewhere in the system, now the fun part is finding it.

    Not really. Mine does it sometimes. Search on here for that turkey pan delete. Try that first and see what changes.
