Idle Speed
INSPECTION
1. Before checking the idle speed, check the following:
^
Ensure the air cleaner element is free from clogging, ignition timing is correct, spark plugs are in good condition, and hoses are connected
properly.
^
Ensure the malfunction indicator light does not illuminate.
2.
Idle the engine.
3. Stop the engine, and turn the ignition switch to OFF.
4. When using Subaru Select Monitor, refer to the following.
^
Insert the cartridge to the Subaru Select Monitor.
^
Connect the Subaru Select Monitor to data link connector.

^
Select (Current Data Display & Save) in the Engine Control System Diagnosis.

Start the engine, and read engine idle speed.
5. When using the tachometer (Secondary pick-up type):
^
Attach the pick-up clip to No. 1 cylinder spark plug cord.
^
Start the engine, and read engine idle speed.
NOTE: 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.
6. Check the idle speed when unloaded. (With headlights, heater fan, rear defroster, radiator fan, A/C, etc. OFF)
Idle speed [No load and gears in "N" or "P" range].
MT Model ............................................................................................................................................................................................. 650 ± 100 rpm
AT Model ............................................................................................................................................................................................. 700 ± 100 rpm
7. Check the idle speed when loaded. (Turn the A/ C switch to "ON" and operate the compressor for at least one minute before measurement.)
Idle speed [A/C "ON" and gears in "N" or "P" range] .......................................................................................................................... 850 ± 100 rpm
NOTE: Idle speed cannot be adjusted manually, because the idle speed is automatically adjusted. If the idle speed is out of specifications, refer
to General Diagnosis Table.
