Idle screw on NG engine

The ECU on my 89 90q can control air by way of the Idle Stabilizer Valve. I
understood this to be the reason you never adjust the idle screw in the
throttle body.

 The ECU can control the amount of
fuel and timing advance, not air. On the CGT it doesn't even get a crack at
the distributor.
