The car runs absolutely phenomenal around town and at WOT. It’s just a new bad idle for some reason. Have reset adaptations several times, tried 93 vs E50, no impact.

Do you run a tank of pump gas between tanks of e mixes? Ethanol is now to gum up injectors over time, to solve this run a tank of pump gas every 2 tanks of ethanol and run some fuel system cleaner before oil changes. Too cylinder lube will completely solve all of this too.
