Engine Jolts Slowing Down - Check Engine Light Flashed
2015 LT/RS w/NPP exhaust. 19k miles. Completely stock.
Was on the highway accelerating, dashboard lit up with check engine light, traction control and stability control lights, center console said “service stability trak syst” In the two years I’ve owned the car I’ve never gotten a single check engine light.
Rest of the night, when I came to a complete stop the car would jolt like a piston misfire or a really rough downshift. Any idea how to fix this?
