I’m looking at a car for sale and the weirdest thing happened…
So this is a 2013 Manual transmission hyunda veloster (non turbo) with 80k miles on it
Car was clean, engine was clean. Idled perfectly and sounded perfect when I revved the engine up from neutral. No sounds at all.
Car drove and shifted very smooth as well, HOWEVER.
I turned the radio and the AC all the way off and I would hear this weird knock noise (literally like a single knock on hard wood) when I would accelerate OR if I took the foot off the gas? it sounded like it came from under the hood but I can’t tell where it was coming from? Sometimes it sounded like the right side? Sometimes the left? It’s not a constant knock and it generally happened if I gave it gas or let off the gas?
I have no idea what the hell this could be? Anyone have an idea?
It happened a lot but it wasn’t constant? I don’t THINK it’s the engine but I’m not a mechanic by any means.
