I have been getting a “service stabilitrak” message for some time now on my 2018 ZL1 1LE. Usually it happens under hard acceleration. Yesterday, it came up under light acceleration, stayed illuminated longer, and I could hear my exhaust tone change as if the valves were opening and closing or the engine was surging. I did not feel any surging, though. The A/C stopped cooling for a minute or so and then it went back to normal. I drove it today and can’t get it to act up again. No codes were set. I have heard that throttle bodies sometimes cause issues like this? Car is cammed and tuned but throttle body is stock. I don’t want to go buying parts without some idea what it could be.
