anyone know what this noise is?? knocking like crazy.

it’s done this for a long time and i changed the oil today but it still knocks hella hard

it dies randomly when accelerating/decelerating or braking

the engine is 2 years old and only been in use for the past 2/3 months, before that it wasn’t touched

if your solution has something to do with idle being too high/ low (i forgot how it sounded in the video lol. probably low) trust me i have adjusted it so many times to so many different rpms, it does this regardless
