[2014 ctsv]

Help!
I have been trying to figure out why I keep getting these codes when going into 5th gear.
They ONLY appear when I drive the car in 5th gea. They disappear after40 miles of driving or so if I don’t use 5th gear cruising.
However, they never appear when driving the car hard.
Car is a 2014 manual sedan, completely stock.

Stock or tuned?

Stock, try cleaning your maf sensor.

You must be hitting a load and rpm in 5th that you don’t hit otherwise.
