Series A
1. Disconnect (-) wire from the negative battery terminal.
2. Drain the engine coolant.
3. Disconnect the accelerator cable.
4. (Models with automatic transmission) Disconnect the throttle control cable.
Note: mark the position of the adjusting nuts, otherwise, if they are in the wrong position, the automatic transmission will shift gears at different speeds.
5. Disconnect the intake air temperature sensor from the air filter cover.
6. Remove the air filter cover and air duct.
7. Remove the throttle body by disconnecting it from the intake manifold.
A) Disconnect the throttle position sensor connector.
b) Disconnect the idle speed control valve connector.
V) Disconnect the air hoses from the throttle body.
Note: It is easy to mix up the hoses when connecting, so mark them before removing them.
G) Loosen the bolts and nuts securing the throttle body.

- Tightening torque - 22 Nm
d) Disconnect the throttle body from the intake manifold and remove the gasket.
e) Disconnect the coolant and air bypass hoses from the throttle body.
Note: Install the throttle body in the reverse order of removing it.
