I have an issue with not being able to adjust my idling speed on my '94 Civic Ex coupe with B18B1, OBD1. I've followed the instructions from this article from Team-Integra.net and when I'm adjusting the idling screw nothing happens at all.

When I disconnect the IACV, the RPM's drop, I get that, but when I go to adjust the idling doesn't really raise or lower, but I do notice that my SRI (short-ram intake) gets louder and quieter as I raise and lower it, but RPM's don't really move at all. Am I doing something wrong?
