Sorry, the manual doesn't provide much info on TB removal or installation. Here is what we have.
1. Remove air cleaner and duct assembly. Disconnect accelerator cable from throttle lever. Disconnect cruise control actuator (if equipped). Remove accelerator cable bracket and set aside.
2. Disconnect electrical connectors and vacuum lines as necessary. Remove 4 bolts (or screws) retaining throttle body assembly to intake manifold. Remove throttle body.
Clean gasket mating surfaces. Clean and oil bolt threads. Install NEW gasket. Tighten bolts to specification. See TORQUE SPECIFICATIONS. To complete installation, reverse removal procedure.
If you need more info please tell me your engine size in liter and the 8th digit of your VIN.
