Super old thread I know… my car is completely stock, 32k miles 2017. Has the exact same issue as all of y’all. Low to med load and even with cruise control on at 2k rpm in 2/3rd gear and it will hiccup or jolt/stutter (whatever you want to say) and then continue and do it again and again with lightly accelerating or just cruising. Any advice? Injectors potentially?
From 50-WOT there is no issue and the car feels perfect. Any advice would be appreciated.

The people discussing this issue ended up fixing by their tuner.

If your car is actually stock and no mods this is most likely a dirty or faulty maf sensor. Take it out, use CNC spray, let it dry for an hour and put it back in. While it's drying have a look at the air filter and clean it or replace it. Issue should solve.

When cruising or light throttle the car will be in closed loop. It will maintain Afr 14.7. if your maf is faulty or dirty it will not read correctly thus your hiccups when cruising or light throttle.
