I own a 1994 honda civic. It drives smoothly but when I stop, there's some subtle rumbling noises coming from the dashboard. This is only when I'm at a full stop. I don't hear any noises as I'm braking or when I'm putting gas, so I don't think it has anything to do with bearings, brakes, rotors, or anything. This doesn't happen all the time. Sometimes my car would make these rumbling, humming noises, but lately it's been happening more often..

 

jackstand, inspect.

 

Post video with sound. Is this a low idle problem?

 

Nvm it's fine! Turns out my lower engine mount was worn out on the passenger side.
