CAUTION:
Do not disassemble intake manifold.
Cover engine openings to avoid entry of foreign materi-
als.
NOTE:
Disregard No. 6 when loosening.
INSTALLATION
Note the following, and install in the reverse order of removal.
Intake Manifold
If stud bolts were removed, install them and tighten to the specified torque below.
Check if gasket is not dropped from the installation groove of intake manifold.
Tighten in numerical order as shown in the figure.
NOTE:
No. 6 means double tightening of bolt No. 1.
Intake Manifold Support
Tighten mounting bolt from “A” to “B” in order as shown in the figure.
NOTE:
Tighten “A” in the figure together with electric throttle control actua-
tor. Refer to EM-21, "
Electric Throttle Control Actuator" for the tight-
ening procedure.
Electric Throttle Control Actuator
Tighten mounting bolts equally and diagonally in several steps
and in numerical order as shown in the figure.
Perform the “Throttle Valve Closed Position Learning” when har-
ness connector of electric throttle control actuator is discon-
nected. Refer to EC-47, "
Throttle Valve Closed Position
Learning" .
Perform the “Idle Air Volume Learning” and “Throttle Valve
Closed Position Learning” when electric throttle control actuator
is replaced. Refer to EC-47, "
Idle Air Volume Learning" .

INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at connections with the following procedure:
1. Apply fuel pressure to fuel lines with turning ignition switch “ON” (with engine stopped). Then make sure
there are no fuel leaks at connections.
NOTE:
Use mirrors for checking on invisible points.
2. Start engine. With engine speed increased, make sure again there are no fuel leaks at connections.
CAUTION:
Do not touch the engine immediately after stopped as engine becomes extremely hot.
