Three-way catalytic converter - gen-
eral information
• 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 condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will help
avoid malfunctions that could damage the
three-way catalytic converter.
• Do not park your vehicle 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), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
• Remember that tampering or unauthorized
modifications to the engine, the Electronic
Control Module, or the vehicle may be
illegal and can cause three-way catalytic
converter or exhaust system overheating.
This includes:
- Altering fuel injection settings or compo-
nents.
- Altering emission system components or
location or removing components.
- Repeated use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.
