First you must detach the Idle Control Valve harness connector and take out the fasteners holding the valve. Do not try to move the Idle Control Valve by pushing or pulling its pintle and ensure you never use any liquid or solvent cleaner when dealing with the Idle Control Valve. After that, take out the Idle Control Valve assembly and its o-ring, clean the Idle Control Valve's o-ring sealing surface, the pintle valve seat and the air passage using carburetor cleaner and a brush made for parts cleaning, but do not use a cleaner containing methyl ethyl ketone. Look for any breaks, signs of wear or deformation on the Idle Control Valve o-ring and change it if it seems damaged. When replacing the Idle Control Valve, check that it has the same shape and exact size as the former one, because they are designed specifically for the car. Determine the distance between the tip of the Idle Control Valve pintle and the mounting flange; if it is longer than 28 mm, use your fingers to gently pull back the pintle without hurting it. Put a little engine oil on the Idle Control Valve o-ring, set the Idle Control Valve assembly in place and attach the parts with 3.0 n.m (26 lb in.) of torque. Eventually, connect the harness for the Idle Control Valve and return its pintle back to its original position.
