Not sure if I am using the correct term " vibration" Have a 2019 base Stingray with 7 speed manual. Bought the car used in fall of 2019. Ever since I had it, idles about 600 rpm and has a slight vibration - car shakes at idle. Maybe a better idea is sitting in a car with a performance cam.
No trouble codes and runs well. I don't detect (hear) any misfire in the exhaust. Brother said back then typical of a high performance sports car. Brother bought a 2025 Z06 and has been driving it around. to me very smooth at idle when I ride or drive it. . He drove my car to the store last night and mentioned your car seems a little rough at idle. If the tach is correct - I do see a slight movement at idle ~ less than 50 rpm. Driving like this for 5 years - do I really have an issue?

My 2019 GS was the same new. I bumped the idle to 800 rpm and it smoothed it out some.

Normal for a C7 if it runs fine besides the rough idle.

Completely normal for the C7. Can't compare this to the C8 Z06 as it has a completely different type of engine.

My 2019 GS M7 bought new idles like hell. If I feather the gas ever so slightly another 50-100 rpm's it smooths out. I have no way to raise the rpm's so I live with it, no big deal.

Used a Diablo I3 to adjust rpm. Also turned off the AFM/DOD and CAGS (stupid feature of GM)

I noticed the same the first days driving the car, all great but after spirited rides or when finding those dreaded traffic lights, it will idle rough. I purchased a new air filter but it was clean and new already. Got one of those soler throttle bodies and really smoothed the idle thing between other benefits.
I had not seeing the same thing happened again, so happy camper here. Mine is also a m7

Don't have to worry about that with a M7 and my CAGS hardly ever comes on. Not paying $417 for a tuner to use once for rpm's.
