Starting a cold engine causes resonance throughout the body.

[Grenadian]

Hi, bros,
My car sounds different from yours.
When I start it, there is a significant resonance throughout the car.
When I drive it, it goes away.
This vibration is not a vibration of a specific part, but a resonance of the entire body.
When I step on the brake while waiting at a traffic light, the vibration reaches its peak.
This vibration is not a vibration of a specific part, but a resonance of the entire body.

Is this normal?

It’s normal especially when it’s new. Been discussed quite a lot regarding idling vibration. The root cause is the heavy duty engine mounts which will settle with mileage. It will vibrate all the heat shields in the engine behind the air box which can be adjusted to minimise. Adjust heat shield underneath the car. Also it may vibrate behind the dashboard area (but only some). Do a search on this forum (vibration at idle).
