I got it from the Helm manuals for 2 former cars. '95 Integra & '98 Accord. It's the last part of the 'set base idle' procedure. It seemed to work for the Integra, but the Accord never really displayed a messed-up idle.

The 'bad idle control' sounds like he means the IACV (Idle Air Control Valve). That's #9 on the back of the intake manifold.
