- Disconnect the purge hose (6) from the evap system purge control solenoid valve. (E-33 only)
- Remove the clamp (7).
- Disconnect the isc valve coupler (8).
- Place a rag under the fuel feed hose (9) and disconnect the fuel feed hose from the fuel pump.
 For e-33
models, drain fuel from the fuel tank before disconnecting the fuel feed hose to prevent fuel leakage. |
- Loosen the throttle body clamp screws, left and right.
- Lift up the throttle body from the intake pipes.

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.
Refer to “isc valve reset” and “tp reset” .

Crankcase emission control system
description
The engine is equipped with a pcv system to prevent discharging crankcase
emissions into the atmosphere. Blow-by
gas in the engine is constantly drawn into the crankcase, which is returned to
the combustion chamber through the
pcv (breather) hose, air cleaner and throttle body.
