b. Loosen mounting bolts in reverse order as shown in the figure,
and remove electric throttle control actuator and gasket.
CAUTION:

Handle carefully to avoid any shock to electric throttle
control actuator.

Do not disassemble.
5. Disconnect harness, power steering piping, vacuum hose and PCV hose from intake manifold, and move
them aside.
6. Remove intake manifold support and gasket.
7. Disconnect sub-harness from fuel injector. Refer to EM-34, "
Removal and Installation (QR20DE)" .
8. Loosen mounting bolts and nuts in reverse order as shown in
the figure, and remove intake manifold (with fuel tube and fuel
injector assembly) and gasket.
CAUTION:

Do not disassemble intake manifold.

Cover engine openings to avoid entry of foreign materi-
als.
NOTE:
Disregard No. 6 when loosening.
9. Remove fuel tube and fuel injector assembly from intake manifold. Refer to EM-34, "
Removal and Installa-
tion (QR20DE)" .
10. Remove EVAP canister purge volume control solenoid valve from intake manifold, if necessary.
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-20, "
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" (WITH EURO-OBD) or EC-560, "Throttle Valve
Closed Position Learning" (WITHOUT EURO-OBD).

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" (WITH
EURO-OBD) or EC-560, "
Idle Air Volume Learning" (WITHOUT
EURO-OBD).
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 engine immediately after stopped as engine becomes extremely hot.
