NOTE:
After installation, it is necessary to re-calibrate the electric throttle control actuator as follows:
1. Perform the ″Throttle Valve Closed Position Learning ″ when harness connector of the electric throttle con-
trol actuator is disconnected. Refer to EC-682, "Work Procedure"
.
2. Perform the ″Idle Air Volume Learning ″ when the electric throttle contro l actuator is replaced. Refer to EC-
683, "Work Procedure".

• Using straightedge and feeler gauge, inspect the surface distortion of the intake manifold. Refer to EM-146, "Removal and Installa-
tion".
INSTALLATION
Installation is in the reverse order of removal. Fo llow the procedure below for specific tightening sequences
and procedures.
CAUTION:
Do not reuse intake manifold gaskets.
• Install intake manifold nuts and bolts in two steps in the numerical order as shown.
NOTE:
After installation, it is necessary to re-calibrate the electric throttle control actuator as follows:
1. Perform the "Throttle Valve Closed Position Learning" when harness connector of the electric throttle con-
trol actuator is disconnected. Refer to EC-682, "Work Procedure"
.
2. Perform the "Idle Air Volume Learning" when the electric throttle control actuator is replaced. Refer to EC-
683, "Work Procedure".
3. Install the quick connector. Refer to EM-163, "Removal and Installation"
.
INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at the connections as follows:
1. Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections. WARNING:
Do not touch engine immediately after stopping as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
