Or are you driving around with the nannies on and complaing about them not doing their job without messing with your throttle inputs?

haha, no. nannies are off during this issue.

i assume you mean stabilitrak when you say ECS?

Yes, the electronic stability control, messed up the acronym. I might need more time behind the wheel to see if I can experience what you guys are saying. It just caught my eye that I didn't see any 2020s or 2021s posting about the issue.

I know that this thread is old but I want to put this link out there: https://www.camaro6.com/forums/showt...ake+hesitation . My 2017 1LE 1SS (18,500 miles) is stumbling upon low throttle inputs at and below 3000RPM. And it's been getting progressively worse. At first it was so slight that I thought that I was imagining it. It has some mods including a Tony Mamo ported/polished TB that was installed very early in the car's mileage. I still have my original TB in the basement, I'll swap them this weekend and report back on what I see on the Mamo and how it drives with the stocker. But if you check out the thread I linked it may explain this lag, at least in some situations. TLDR: Throttle bodies with some miles on them get a bit of slop in their motion, perhaps causing strange acceleration and decel issues. New throttle bodies from GM are a different part number, so....maybe GM figured something out.
