Oldsmobile 19333268 Valve Asm,Idle Air Control

For the purpose of removal and replacement of idle control valve assemblies there is a need to unplug the electrical connection to the valve. To remove the valve, you require an appropriate wrench this being 1 1/4 inches (32mm) in diameter. To install, reverse all these processes while it is recommended that it is done within one and an 1/8 inch (28mm) from the motor housing to the tip of the cone to prevent damage. A new gasket must be had and the ignition switched on and off to allow the idle control valve to adjust. Thus determine if the replacement valve is either of Type 1 which has a collar at the electric terminal end of the valve or the Type 2 that does not have the collar. If the measured distance is more than this distance, for Type 1, apply downward pressure on the valve to reset it; for Type 2, push in the retaining spring while rotating the valve anticlockwise, then release the spring and align the flat end of it with the counterpart part of the valve.

The throttle body can be replaced without removing it from the intake manifold or fully disassembling it. First off, reduce the fuel pressure and separate the cable from the negative terminal of the battery. Get rid of air cleaner housing assembly, adapter, and gaskets. Then take apart fuel meter cover and injector by unscrewing fuel meter cover retaining screws and removing injector electrical connector. Carefully open up the injector from the fuel meter body; then remove if necessary for cleaning. Remove old gasket and cleanse out the entire fuel meter body. Take apart this unit by taking away small O-ring as well as fuel filter. In case of any malfunctioning with a fuel injector, never try to fix it; just replace it with a new one.The new clean small O-ring should be lubricated before pushing it in over nozzle end of injector.Install steel backup washer and lubricate new large O-ring prior to placing on top of backup washer.Put injector into position while making sure that it is completely seated within product cavity of metering.Replace old gaskets with brand-new ones followed by dust seal which can be held in place through thread locking compound.Now connect electrical connector to an outlet valve then reassemble an air cleaner.Idle air control (IAC) valve requires removal of its electrical connector then use wrench for removing valve.Measuring distance extended by valve will help you make adjustments where necessary.Supplied gasket should be fitted once entirely cleaned before plugging in electrical connector.Start engine once again after replacing air cleaner.As for throttle position sensor (TPS), unscrew Torx screws and disengage TPS.Putting new TPS means ensuring that lever slips into slot on throttle body.Re-install this air cleaner assembly so that cable is attached back to negative terminal on battery.Fuel leaks must be checked using ignition switch turned on but not engine itself being switched on because they are dangerous when motor vehicle is driven around all other road users including pedestrians.

Install new O-rings lubricated with engine oil.
