Three-way catalytic converter cautions
pg. 66
●
Keep your engine properly tuned. Certain engine malfunctions,
particularly involving the electrical, fuel or distributor ignition systems,
may cause unusually high three-way catalytic converter temperatures. Do
not continue to operate your vehicle if you detect engine misfire,
noticeable loss of power or other unusual operating conditions, such as
engine overheating or backfiring. Aproperly tuned engine will help avoid
malfunctions that could damage the three-way catalytic converter.
●
Remember that tampering or unauthorized modification to the engine or
the vehicle may be illegal and can cause three-way catalytic converter or
exhaust system overheating. This includes:
-Altering fuel injection settings or components.
-Altering emission system components or location or removing
components
-Repeated use of leaded
fuel.
●
Do not park your car
over combustible
materials, such as grass
or leaves, which can
come into contact with
the hot exhaust system
and cause such materials
to ignite under certain
wind and weather
conditions.
●
Excessive starter
cranking (in excess of
one minute), with an
intermittently firing or
flooded engine, can
cause three-way catalytic
converter or exhaust
system overheating.
NOTE: Unleaded fuel is
required for cars with
