Spark plugs
Spark plugs must fire properly to assure proper engine
performance and emission-control.
Do not reuse spark plugs by cleaning or regapping. Spark
plugs should be replaced at the mileage specified on the
scheduled maintenance chart.
Your vehicle may be equipped with standard type spark
plugs or iridium tipped ones. Iridium tipped spark plugs
are identified by blue marks on the ceramic. They do not
require replacement as frequently as the conventional
type spark plug and are designed to last much longer.
NOTE
: Use the recommended or equivalent spark plugs
listed under “Engine specifications” on page 377.
Use of non-recommended plugs will cause engine dam-
age, loss of performance or radio noise.
Ignition cables
The ignition cables should be kept clean, properly con-
nected, and fully seated. Terminals should be fully seated
and should not be removed from the distributor or coil
towers unless they are damaged or cable testing indicates
high resistance or broken insulation. Cracked, damaged,
or faulty cables must be replaced.
Distributor cap and rotor
Check the distributor cap and rotor to maintain proper
function and good emission control.
