IGNITION
2) Carbon fouled:
Dry fluffy carbon deposits on insulator and elec-
trode are mostly caused by slow speed driving in
the city, weak ignition, too rich fuel mixture and dirty
air cleaner.
3) Oil fouled:
Wet black deposits show oil entrance into the com-
bustion chamber through worn rings and pistons or
excessive clearance between valve guides and
stems.
4) Overheating:
White or light gray insulator with black or brown
spots and bluish burnt electrodes indicate engine
overheating. Moreover, the appearance results
from incorrect ignition timing, loose spark plugs,
wrong selection of fuel, hotter range plug, etc.
D: ADJUSTMENT
Clean the spark plugs using a wire brush. Clean
and remove the carbon or oxide deposits. But do
not wear away ceramic insulator at this time. If de-
posits are too stubborn, replace the spark plugs.
After cleaning the spark plugs, measure the spark
plug gap using a gap gauge.
NOTE:
Do not use a plug cleaner because the spark plugs
are applied with iridium tip.

0.7 — 0.8 mm (0.028 — 0.031 in)

General Description
INTAKE (INDUCTION)
B: CAUTION
•Wear work clothing, including a cap, protective
goggles and protective shoes during operation.
•Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
•Keep the disassembled parts in order and pro-
tect them from dust and dirt.
•Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
•Be careful not to burn yourself, because each
part on the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and
nuts to the specified torque.
•Place shop jacks or rigid racks at the specified
points.
•Before disconnecting connectors of sensors or
units, be sure to disconnect the ground cable from
the battery.
