leakage.

6.

Remove electric throttle control actuator as follows:

a.

Disconnect harness connector.

b.

Loosen mounting bolts in the reverse order as shown in the fig-
ure.

CAUTION:

• Handle carefully to avoid any shock to electric throttle

control actuator.

• Never disassemble.

7.

Remove the following parts:
• Vacuum hose
• PCV hose
• High pressure piping from intake manifold: Refer to 

ST-64, "Exploded View"
