New here and I’ve got a new to me 2008 Ram 1500 Hemi 4x4. Got a check engine light on for small evap leak. I changed the oil and filter Sunday. Driving it Tuesday it started making a rumbling sound like as if it were straight piped. Around 2,000 rpm it’ll give a shake and the rumbling, I guess like it’s not getting air or maybe a hose issue?
hopefully you can hear it on attached short video

anyone have an idea of where and what I should look at first??

thanks

David
