Strange sound when revving
Hey guys... i figure this is the place to ask cause i know the guys at honda wouldn't know what to tell me... but sometimes my car makes a strange noise when i rev past 5k ... sounds like something is vibrating and it feels harsh.. uninviting! .. and it keeps doing that for a while and eventually stops and i can go to 9k with no issues. then for a long while it won't happen and then it comes back... i think it happens more when it's cold...but i may just be imagining. The vibration sounds metallic coming from the engine somewhere or something...
Any ideas?
