10.6 - Adjusting Idle Speed ( )


Set the throttle plate gap to .002(.05mm). This is the gap between the throttle plate and the wall. To do this right, you should remove the throttle body and clean it with some throttle body cleaner and then set the gap. The throttle body/ plate gets gummed up from the crankcase vent being before the throttle.

After setting the gap, reassemble the throttle body and all parts, clamps, wires, etc.

Warm up car,
ac off,
transmission in park,
turn key off,
Turn key on but don't start car and wait 15 seconds then disconnect connector to iscv.
The iscv is just forward of the throttle body, close to the cruse control bellows.
turn key off,
hook up iscv connector,
turn key on but don't start car...wait 15 seconds,
disconnect iscv connector, (your winding the iscv closed)
leaving the iscv connector disconnected, start the car.
turn the idle speed air bypass screw on the iscv using a 7\32 inch Allen wrench till the rpm is 550 to 600.
Hook up the iscv connector.

You're done.

If the static idle is not set correctly, the rpms will hunt around. The computer is only supposed to raise the idle from base due to a load, so if the base idle is not set right the computer doesn't know what to do, hence the hunting.
