How do you change air idle control valve on 1995 Saturn?

Answer 1

Just to be sure, the air idle control valve is a little plunger device mounted on the throttle body that regulates the idle speed. This a fairly easy procedure. It is possible to remove it without removing the throttle body but is a lot easier with the throttle body off. Loosen the clamps on the air duct and remove the duct. Carefully pull off all vacuum lines and disconnect the plug to the throttle position sensor and the idle control valve. The control valve is the one at the bottom of the throttle body. Remove the two bolts holding on the throttle body and remove the throttle body. The accelerator cable end should slide right out. On my vehicle the throttle body separated from the gasket cleanly. If the gasket tears apart you will have to scrape the old one off and replace with a new one. Best get a new gasket with the control valve. Now remove the two torx screws holding the control valve and pull it out. The new control valve should have the plunger fully retracted. If it is not then carefully push it down before installing. Insert the new one being careful to not bind the O ring. Reverse the above for assembly.
