LexusRide Posted July 27, 2010 Share Posted July 27, 2010 Gentlemen, Car was hard to start and had a rough idle. The problem was carbon/dirt had fouled the ICV (Idle Control Valve). This valve's function is to provide path for air to bypass the butterfly assembly in the throttle body at idle; with out it functioning correctly the engine is starved for air. This is a common problem that can be remedied with a good cleaning process with carburetor cleaner. When white electrical coil is removed from the ICV, it exposes a small pencil sized metal stud. This stud needs to rotate 1/8 turn feely and then one more additional 1/8 turn with some spring resistance for a total of a 1/4 turn. If this stud does not rotation freely, then the ICV will need to be cleaned. 08/092005 - No new gaskets were needed, used old ones with no problems. - Caution, when removing the ICV from the throttle body. Great care must be taken not to strip out the four screw heads when breaking the factory torque. A very tight fitting screw drive is essential. - DO NOT disassemble the ICV assembly after removing it from the throttle body; it has critical settings that may not be able to be maintained if reassembled.
