Removing
Models with 1.6 liter engine
1. Disconnect the negative battery cable.
2. Remove the air filter cover following the instructions in subsection 6.3.2.2.
3. Compress the mounting clips and disconnect the connectors from the throttle potentiometer, auxiliary air supply valve, air flow sensor, and idle speed increase solenoid valve.
4. Disconnect the accelerator cable from the throttle cam. Unscrew the locknut and adjusting nut, and remove the cable sheath from the mounting bracket.
5. Remember or mark the installation position of all vacuum and vent hoses in order to connect them correctly when installing the throttle body, then loosen the mounting clamps (where installed) and disconnect the hoses from the throttle body.
6. Loosen the mounting clamps, then disconnect the cooling system hoses on both sides of the throttle body and plug the hose holes. Do this quickly to minimize coolant loss.
7. Loosen and remove the mounting bolts securing the throttle body to the intake manifold and remove the throttle body from the vehicle. Remove the gasket and discard it; when installing, use a new one. Plug the intake manifold opening with a clean rag to keep dirt or foreign matter out of the intake manifold.
Models with 2.0 liter engine
8. Loosen the clamp and disconnect the intake air line from the throttle body.
9. Disconnect the connector from the throttle potentiometer.
10. On models "Phase I" carefully disconnect the throttle linkage rod from the ball joint on the throttle body.
11. On models "Phase II" Disconnect the accelerator cable from the throttle cam. On automatic transmission models, also disconnect the downshift cable.
12. On all models, release the mounting clamps, disconnect the coolant hoses from the throttle body and plug the hose holes. Do this quickly to minimize coolant loss.
13. On all models, note or mark the installation position of all vacuum and vent hoses in order to properly connect them when installing the throttle body, then loosen the mounting clamps (where installed) and disconnect the hoses from the throttle body.
14. If necessary, remove the intake manifold mounting bracket to gain access to the throttle body mounting bolts.
15. Loosen and remove the mounting bolts securing the throttle body to the intake manifold and remove the throttle body from the vehicle. Remove the gasket and discard it; when installing, use a new one. Plug the intake manifold opening with a clean rag to keep dirt or foreign matter out of the intake manifold.
Installation
1. Installation is carried out in the reverse order of removal. Before installing, check that the mating surfaces of the throttle body and intake manifold are clean and even.
2. Install a new gasket on the intake manifold. Install the throttle body to the intake manifold, then diagonally tighten all mounting bolts to the correct stage 1 torque, then tighten them to the correct stage 2 torque (see subsection 6.3.2.1).
3. Check that all hoses are correctly installed and, if necessary, secure them with mounting clamps;
4. After installation is complete, adjust the accelerator cable following the instructions in subsection 6.3.2.3.
5. On models with automatic transmission, adjust the downshift cable following the instructions in subsection 9.2.4.
