SLE 2.7L L4 shudders @ 2000-3000RPM

[K Kroeker]

Looking to get some insight into why a 2023 GMC Sierra 1500 8-speed SLE 2.7L L4 would shudder when accelerating around 80-100 km/h (50mph to 62mph) between 2000-3000RPM. It began doing this last winter, and hasn't been used since, but it continues to have this issue. I used to be able to sustain the shudder for longer, but now it only lasts about 2 seconds.

There's a new PI on 2023-2026 L3B shudder.  Possible faulty front oxygen sensor.

 

Dealer can pull up PIP6060A and give it a read.
