I'm not sure that the screw in the top of the throttle-body is the idle
level control screw, I think it's a stop for the throttle. There should
be another screw on the linkage on the side of the throttle-body for
setting the base idle RPM. Check Bentley to be sure. Undoubtably varies
from model-to-model, but I'm pretty sure that the screw on top is NOT the
idle adj on ur-Qs and 4000Qs.....
