Yep it happened to me ... removed the intake and never happened again. That said I removed the JB4 at the same time so it was either one of them

My only mods are the BMS Intake and BMS Stage 1 Tune, pretty easy setup and never had a CEL. I have a feeling the intake might be the culprit, the Stage1 may not be tuning out the which could make the car run lean . Also I'm told MAFs sensors are picky with intakes on our cars.

Has this happened anyone? Hoping to hear from others before I take the time to remove my intake, which I really prefer to keep in the car.

Thanks!
