1. Foreword
This chapter describes major inspection and service pro-
cedures for the engine mounted on the body. For proce-
dures not found in this chapter, refer to the service proce-
dure section in the applicable chapter.
2. Ignition Timing
A: MEASUREMENT
1) Warm-up the engine.
G2M0094
2) To check the ignition timing, connect a timing light to #1
cylinder spark plug cord, and illuminate the timing mark
with the timing light.
3) Start the engine at idle speed and check the ignition
timing.
If the timing is not correct, check the ignition control sys-
tem.
Ignition timing [BTDC/rpm]:
14°±8°/700 (MT)
20°±8°/700 (AT)

3. Engine Idle Speed
A: MEASUREMENT
1) Before checking idle speed, check the following:
(1) Ensure that air cleaner element is free from
clogging, ignition timing is correct, spark plugs are in
good condition, and that hoses are connected properly.
(2) Ensure that malfunction indicator light (CHECK
ENGINE light) does not illuminate.
2) Warm-up the engine.
G2M0096
3) Connect Subaru Select Monitor or the OBD-II general
scan tool to data link connector.
CAUTION:
When connecting Subaru Select Monitor, turn ignition
switch to OFF.
4) Start the engine and measure engine speed.
NOTE:
Engine speed is indicated on Subaru Select Monitor by
selecting “MODE F04”.
G2M0097
NOTE:
When using the OBD-II general scan tool, carefully read
its operation manual.
When Subaru Select Monitor is not used, attach the
pickup sensor on tachometer (Secondary pickup type) to
#1 cylinder spark plug cord.
This ignition system provides simultaneous ignition for
#1 and #2 plugs. It must be noted that some tachometers
may register twice that of actual engine speed.

5) Check idle speed when unloaded. (With headlights,
heater fan, rear defroster, radiator fan, air conditioning, etc.
OFF)
Idle speed (No load and gears in neutral (MT) or N or
P (AT) position):
700±100 rpm
6) Check idle speed when loaded. (Turn air conditioning
switch to“ON”and operate compressor for at least one
minute before measurement.)
Idle speed [A/C“ON”, no load and gears in neutral
(MT) or N or P (AT) position]:
850±50 rpm
CAUTION:
Never rotate idle adjusting screw. If idle speed is out
of specifications, refer to General On-board Diagnosis
Table under “2-7 On-Board Diagnostics II System”.
