Rough idle + flashing Check Engine light + stability track?

[Ozer]

I searched but hard to find anything on this combo, if anyone knows of a thread please attach it.

 

2014 SLT 5.3 130k miles..

Periodically i get rough idle which then throws the light on which is flashing and at the same time traction light comes on, one where the truck is fishtailing lol

Now, at 120k miles i put in brand new plugs, wires and 8 new coils (while i was chasing a misfire issue which turned out to be TC shudder = new trans )

There are no codes stored, it happened twice and both times i connected the reader, even while it was running and not running, still no codes.

Once you turn it off and its off for a bit, truck starts up like nothing happened and everything is fine.

 

Just seeing if anyone had the same issue and what it could be causing it. I checked all ignition connections after it happened, all was fine.
