Installation
Installation is in the reverse order of removal. Pay attention to the following points:
- connect the primary injector couplers (1) and secondary injector couplers (2) to the respective fuel injectors. Make sure that each coupler is installed in the correct position. The color on each lead wire refers to the appropriate fuel injector.
- Connect the throttle cable no. 1 (3) And throttle cable no. 2 (4) To the throttle cable drum.
|
- Loosen each throttle cable lock-nut.
- Turn in each throttle cable adjuster fully and locate each outer cable so that the clearance “a” is 0 – 1 mm (0 – 0.04 In).
- Tighten each lock-nut.
Tightening torque throttle cable lock-nut: 4.5 N·m (0.45 Kgf-m, 3.0 Lbf-ft)
- Adjust the throttle cable play. Refer to “throttle cable play inspection and adjustment” in section 0b .
- Reset the isc valve and tp sensor learned values.
