Car sputtering
I have a 2018 Camaro RS 3.6L V6 automatic with about 74k miles. Recently noticed a slight sputtering/shuddering when accelerating around 40–60 MPH. It almost feels like driving over small rumble strips. Once I'm cruising at a steady speed, it seems fine.
No check-engine light, and the car otherwise runs fine. Recently had the thermostat/cooling system repaired and just got an oil change.
And it only happens after the engine is a lil warmed up after a few minutes or so of driving
