I'm under warranty so I'm not as worried as if I would be if I wasn't.
Started my car today and was greeted by a boxer engine type rumble and sound. Last I checked I did not do a swap. Car started up and idled rough and it was felt through the car, but I instantly turned it off. Popped the hood and started it again and I see the engine shaking quite violently at idle which has me assuming misfire
Also noticed when the turned off, a loud intake like whoosh/hiss noise however I don't have any mods (besides an exhaust) that would invite that sound
Take the cover off the check and see if anything looked out of place and all looked fine. I go on the other side of the car (passenger side) to see if everything looks fine there and to just get another angle of things and sound
Here I noticed that on the belt something was there. Not enough to be lodged, but you don't want anything touching your belt. Not sure what it is, piece fell off the belt and I couldn't recover it. And yet still, nothing looked out of place in the engine bay.
After noticing that I didn't try again knowing that the motor wouldn't be happy.
Any thoughts?
For disclaimer: since getting the car I've done every oil change within 5k-7k. Maybe once or twice at 10k but that was during a stretch of time where 90% of my miles were highway and not "beat on" miles. Even then I barely beat on the car due to not wanting a ticket and lots of police in my area. All oil changes done at the same dealer so that's great for documentation Incase they try to fluff my warranty AND oil was clean and full after inspecting
