INSPECTION AND MAINTENANCE
EXAMPLE
54G106
NOTE:
If your engine is equipped with the high-
tension cord type ignition wiring and you
experience some firing problem of spark
plugs, such as, hard engine-starting, mis-
fire etc., the cause may be located not only
on spark plugs but also on deteriorated
ignition wirings (generally, used for more
than 80000 km or five years). If spark plug
to the
replacement does not solve the problem,
have the ignition wiring and other ignition
system inspected by your SUZUKI dealer.
