I've got a 2016 Stingray M7. Headers, intake manifold, CAI, and a tune. It was driving just fine to the grocery store and when I came back to my car to leave, it would try to start, but wont start. Says engine power reduced. I scanned it and it gave me 14 error codes. This hasnt happened to me before. I've had it for about over 3 years now. Anyone have any ideas about what it could be?

Reason: spelling
Sounds like a weak battery with all those “voltage” DTC’s…get the battery checked and or changed and erase all trouble codes and see what comes back…what part of Florida are you in ??
The codes indicate that 5V Reference 3 and 5V Reference 4 are either shorted to ground or shorted to voltage. 5V Reference 3 connects to the accelerator pedal position sensor 2 and the manifold absolute pressure sensor. 5V Reference 4 connects to the accelerator pedal position sensor 1 and the throttle position sensor. I would start by checking the reference voltages at the accelerator pedal with the pedal connected and disconnected.
