REMOVAL & INSTALLATION
See Figure 1
Any time a high fuel pressure line is disconnected, a large amount of gasoline will spill out. Always slowly loosen the connection and place a container under it. Plug the connection afterwards.
- Disconnect the negative battery cable.
- Drain the engine coolant.
- Tag and disconnect all lines, hoses or wires that lead from the throttle body. Position them out of the way. Remove the air intake connector and the air cleaner hose.
- Unscrew the mounting bolts and remove the throttle body and gasket.
- Install the throttle body using a new gasket and tighten the mounting bolts to 9-13 ft. lbs. (12-18 Nm).
- Connect the air cleaner hose and the air intake connector.
- Reconnect all lines, hoses and wires.
- Fill the engine with coolant and connect the battery cable.
- Check that the throttle linkage moves smoothly.
- Start the engine and remove the hose from the vacuum port.
- With your finger, check that there is no vacuum at idle and that there is vacuum at anything other than idle.
- Unplug the electrical connector from the throttle position sensor.
- Insert a flat feeler gauge between the throttle stop screw and the stop lever.
- Using an ohmmeter, check the continuity between each terminal on the sensor.
- Check the dash pot as detailed previously in this section and also in Engine Performance and Tune-up .
