hey guys. i tried the civic forum first, thinking it might be a common problem, but to no avail, and a degree of rudeness after stating i drive something that didnt have an H on the wheel.
anyway long story short, the gf comes to me about a week ago saying when the car is idle in drive (say at a light) it vibrates like crazy. she said it also has a loud knock. im thinking motor mount. all the mounts are tight, and i actually had to replace them all in early '12 because the trans shop in alabama didnt tighten them, and they all cracked on the way to memphis. (before i moved back home).
so all the mounts are good, i tried thicker oil thinking it might help, not that.
its got new plugs and coild as of 15k ago, no codes, no lights, drives fine. i am thoroughly stumped.
the only thing i can think is maybe a flywheel bolt or something. given thaat the motor mounts weren't tight, im wondering if they forgot to tighten other things.
the noise is most noticeable around 1800rpm. i took a video. thanks alot for any help guys!
