There is a low rumble when it idles. Its very irritating I am not sure what it is, it has New Tune up + Air Filter. How do you increase idle, I just want to do it like a little bit so I can get it to stop shaking.
it should be the same as a b18a1...if so, theres a srew near the throttle body that u turn counter clockwise or the other way...but you gotta do some computer work to do the job right
