I have a 97 DX Civic (non-VTEC) and I've got a very low idle, to the point where its starting to shake my shift knob violently. I'm fairly confident that it is a problem with the IACV needing to be adjusted, however my Haynes manual isn't helping in finding the damn thing. If anyone could provide me with some pictures/drawings/advice on finding this thing and adjusting it, that would be pretty sweet
