Engine Idle Speed
Refer to Important Safety Precautions on page 33.
Remember, idle speed adjustment is not a “cure
-
all” for other problems in your engine’s PGM-FI
system. Adjusting the idle speed will not
compensate for a fault elsewhere.
The engine must be at normal operating
temperature for accurate idle speed adjustment.
When pushed in, the fast idle knob acts as the idle
adjustment screw.
Turning it counterclockwise results in a faster/
higher idle speed.
Turning it clockwise results in a slower/lower idle
speed.
1. If the engine is cold, start it and warm it up 3
minutes. Then shut it off.
2. Connect a tachometer to the engine.
3. Shift the transmission into neutral. Start the
engine.
4. Adjust idle speed with the fast idle knob (1).
Idle speed: 1,800 ± 100 rpm
