CT5V-Blackwing
Hello, have about 1,000miles on the 5 blackwing. When stopped I notice the idle.. it kind of gently shakes the car and the tach is slightly moving up and down. Is this common of the LT-4? Just wondering because my car also had some higher delivery miles.

That’s what makes it an ice and not an e.v. , personality , raw , the smell of gas and oil , it’s alive .

Probably too early at 1000 miles but if the vibration worsens, check for a torn or leaking motor mount.
