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.
Did you check for codes at autozone?
Auto zone cannot read anything if there is no current CEL on the vehicle. Just left there.
