So update. This issue went away with warmer weather. I thought maybe the problem fixed itself lol. However, now with the cooling weather, the issue has returned. Now the real funny thing is, it seems to do it the worst between 50 and 70 degrees. When it's real cold, it isn't as bad, but still present. In the heat it's never present.
It's only at idle, or once it's been under load at speed and then I let it coast. As in climbing a hill and then coasting down. Once I give it throttle and it's under load again, the light goes out. So it makes sense what was previously mentioned about a leaking gasket causing a lean condition and the compensation from the ecu puts it in a rich condition once the rpms are down. I actually have a set of metal intake gaskets that came with my Texas speed DoD delete kit. I'll swap these out in the coming weeks and see if that helps
