All the sudden yesterday, my car leaned right the hell out, even died one time. I tried increasing the fuel and changing the fuel offset, but I cannot get it to idle lower than 16-18 afr.


I even tried using a couple of different basemaps and increasing the fuel offsets for more fuel, I still cannot to get it to idle properly:

Any help would be greatly appreciated to get my car running properly again.

Oh, I have not touched my battery offset because I do not what's a safe increment to play around with.
