i am betting its the injectors

pretty much at the three year anniversary (40-50K miles) it happens to almost everyone

you are still on manuf warranty - go get them replaced. it will keep happening
Somewhere there is a way to induce a cel if it is your injectors. I think by driving in sport mode and downshifting to make it run hard at high rpms. The bad injectors can't feed enough fuel and it will throw the CEL. I would want to take it in with the CEL showing.
Interesting point! Yeah still nothing driving normal mpg still 16.5, drives hard is M mode even when shifting. Don't want to waste my time at dealer because of no CEL. I'll give it another week and see.
