Does anyone else’s make this noise at idle




it's always gonna do it the first few seconds when you start the engine cold, but it should quiet down a bit after a few seconds.
on some cars it quiets down and goes away, on others it quiets down but is still there and never goes away. There's no rhyme or reason to it, as far as I know.
