436 MAINTAINING YOUR VEHICLE

Spark Plugs

Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug, malfunctioning spark plugs can damage the cata-
lytic converter. For proper type of replacement spark
plugs, refer to Fluids, Lubricants and Genuine Parts for
correct spark plug type.

Engine Air Cleaner Filter

Refer to the "Maintenance Schedule" in Section 8 of this
manual for engine air cleaner filter maintenance inter-
vals.
NOTE: Be sure to follow the "dusty or off-road condi-
tions" maintenance interval if applicable.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc.) removed. Failure to do so can result in
serious personal injury.

Catalytic Converter

The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
