Attention! See precautions in subsection 6.3.1 before starting work. If you think an injector has failed, try cleaning it with an appropriate injector cleaner such as Holts Redex Injector Treatment.
Removing
1. Disconnect the negative battery cable.
2. Remove the air filter cover (see subsection 6.3.1.2).
3. Walk along the wire from the injector and disconnect the connection connector.
4. Release pressure from the fuel system (see subsection 6.3.1.7).
5. Unscrew the two fixing screws of the injector cap, then remove the cap and gaskets.
6. Remove the injector from the throttle body and remove the sealing washers and seals.
Attention! The injector can sit firmly in its seat. In this case, do not try to pull it out by the wires. Remove the upper part of the throttle body and push the injector out of its socket.
7. If the injector needs to be replaced, it is necessary to release its wires from the connection connector.
8. To do this, remove the fastening clip at the back of the connection socket, then, using a small screwdriver, release the corresponding wires and push their terminals out of the connection socket.
9. Remember or mark the installation position of each of the wires in the connection socket and try not to damage the wire terminals when removing them.
10. If you do not want to disassemble the connection connector, the injector can be removed together with the engine idle speed increase device and an additional air supply valve.
Installation
11. Installation is carried out in the reverse order of removal.
12. When installing, pay attention to the following points.
13. Install a new sealing washer and injector seals, and new gaskets for the injector cap.
14. When installing a new injector, insert the terminals of its wires into the corresponding sockets on the connection connector.
15. Check that they are securely fixed, then install the mounting clip on the back of the connection connector.
10. Check that the wires are correctly positioned in the connection socket. If not, the injector will not work properly after connecting the connection connector.
