Runs rich for no reason. turbo 6.0
Car is fully tuned for a few years with no tuning issues. Same setup for years to. Out of the blue I will start it up and it stays around 11.3 to 11.7 afr, idling cruising doesn't matter. I go wot and it goes off the charts rich.
This happens about 1 out of 10 drives. Most times it runs perfect at 15.0 afr idle cruise and 11.5 wot.

Some times I will drive for 30 mins of the high way and eventually it will just right to 14.7 - 15 afr out of no where. Other times it stays rich for the whole ride, i park it come back a couple hours later and it runs perfect. Most times it just runs perfect.

Then look for the problem. It should reveal all.
And are both banks rich ? does the narrowband also correspond as rich ?
