so its not bad, but it does happen, i heard it was the fuel dampening hose? not sure if that is true or not, can someone help me verify?

sounds only like a diesel inside cabin.

2013 infiniti g37 xs

not much noticable, kinda cool at times since it is a beastly engine

 

Failed fuel dampener does make it sound like there's a bad exhaust leak, aka diesel sound. I had it on my G35.

 

What makes it sound like a. Diesel then?
