Are you sure it's the check engine or could it be battery light ? By your description sounds like to me the battery light flickering at idle ,mine will do it when the lone wire going into the top of the alternator becomes disturbed .

I'm positive it's the check engine light. I had the codes ran by the generic obd-ii scanner and nothing showed up. I know diesels have different codes but I was seeing if any of y'all might know what it was before I go buy a true code reader. It does have a small fuel leak coming from somewhere around the fuel filter. Could this have anything to do with it. I just find it odd that the light will come on when you first crank it, then go away when you rev it up and then come back on when the rpms go back to idle
