How do you adjust a new idle speed control motor on a 93 Cadillac deville?

To adjust the idle speed control motor on a 1993 Cadillac DeVille, first ensure the engine is at operating temperature. Disconnect the electrical connector from the idle air control (IAC) motor, then turn the ignition key to the "on" position without starting the engine. Use a multimeter to check the resistance of the IAC motor; if it’s out of spec, replace it. After installation, clear any diagnostic trouble codes and allow the vehicle to relearn the idle settings by driving it normally.
