  Q: How to replace the Fuel Injector, Idle Control Valve and Throttle Position Sensor on Chevrolet Beretta?

  A:

  To replace the fuel injector, disconnect the negative battery cable and, if there is Delco Loc II audio system, the lock out feature should be off. Disconnect the electrical connector at teh injector After that, you have to take of the injector retainer screw and the retainer. Exercise some care when pulling out the injector from the fuel meter body. If reusing the injector change the upper & the lower O-rings where the upper O-ring must be fitted in the groove while the lower O-ring must be flat on the filter element. Place the injector assembly vertically down into the fuel meter body such that the connector end rests at the wire harness grommet opening. Fix the injector shaft to the retainer and screw the retainer to the injector using a thread lock. Responding to the negative battery cable, turning the key to the 'On ' position that pressurizes the fuel system to check the leaks around the injector. Connect electrical connector and then engage the engine to ensure normal working condition. With the pressure regulator assembly, we find that it has a highly compressed spring, and that is why only a dealer or a repair shop may need to fix this part. The IAC valve requires servicing; therefore, turn off the car's battery, take off the air cleaner, and disconnect electrical contacts from the IAC valve. Disconnect the two retaining screws that join the valve to the Throttle Body, and pull it out noting that if reassembling then a new O-ring should be applied. Check distance of the end of pintle to the mounting flange should not exceed 1-1/8 inches if it is greater than this then use a flat head screw driver or any suitable object to squeeze the pintle into the valve assembly and check the extension. Place the valve in the throttle body opening, put and tighten the screws and reconnect the electrical connector. For IAC valve we do not have to adjust anything since it has an automatic reset. To remove the throttle position sensor you must first remove the negative terminal on the battery then remove the air cleaner housing and pull the electrical connector in the sensor. Take out two screws in the mounting area and then pull off the sensor from the throttle body. For installation insert the slot available at the rear of the sensor on the shaft of throttle body and then fasten it with the mounting screw In fact, this type of sensor is no way adjustable. The removal process is simply a mirror image of installation; thus making the process a rather easy one.
