Default Pulsating exhaust sound

Guys,

Would like to know if you guys experience exhaust with pulsating sounds? Happens when in idle. when the engine is warm. Not sure what it is.

Any feedback is great!

I'd first check OBD II to see if any error codes pop up. Then, check and/or replace the spark plugs.

Replacing plugs is relatively inexpensive...

Uh, that's just the sound of an engine running. By definition, an internal combustion works by explosions made in sequence, thus that "pulsing" sound you here.

Cars are inherently a very violent object and it's supremely shocking that they operate as nicely as they do.

Stop worrying, your car is completely normal. Just drive it and enjoy it.

Cars do things like make noises!

^^^ Agree. It's completely normal, nothing to worry about.

Sounds like mine. I always thought mine almost sounds like a diesel when in idle.
