<POOR IDLE ADJUSTMENT> UNSTABLE IDLE SPEED
Probable cause
• Air leakage
• 1 or more cylinders misfiring
• VF voltage abnormality during idling
• Ignition timing off
Note:
When fuel of a low vapor pressure is used in winter, insufficient vaporization may cause unstable idle speed.
Inspect inner vent piping and LPG regulator drain cock
STD.
OPT.
(1) Inspect the installation of the inner vent piping.
Standard: Connected.
(2) Remove the drain plug (STD.), or open the LPG regulator drain cock
(OPT.), remove any tar and close the drain cock again.
Caution:
Be sure to intall the drain plug (STD.), or close the cock after
removing tar.
Drain plug
Close
Open
Replace spark plug
NG
OK
Inspect power balance
Cause one cylinder at a time to misfire
by removing its resistive cord, and
inspect for a drop in idle speed.
Inspect distributor cap and
resistive cord (Refer to parts
inspection and adjustment 10, 11)
Only a
particular
cylinder
NG
OK
Inspect spark plugs
(1) Check that there is no obvious
deposition.
(2) Inspect the plug gap.
Standard:
0.7 to 1.0 mm (0.028 to 0.039 in)
Inspect for air leakage
between the throttle body
and cylinder head.
Repair air

Replace distributor cap and
resistive cord

Inspect compression
(Refer to parts inspection and
adjustment 15)
Inspect initial advance timing
(Refer to page 2-16)
