No adjustment's are possible .. just cleaning or replacing the valve ! IDLE AIR CONTROL VALVE Removal & Installation Disconnect battery negative terminal. Remove connector from Idle Air Control (IAC) valve. See Fig. 14 . Unscrew valve from its location at rear of plenum chamber. Remove sealing washer. To install, fit a NEW sealing washer. NOTE:If same bypass valve is being refitted clean any previous sealing compounds from threads. Apply Loctite 241 to threads of valve before reassembly.

Tighten valve to specified torque. See TORQUE SPECIFICATIONS . To complete installation, reverse removal procedure.
