Spark Plugs
Inspect/replace the spark plugs as outlined in the periodic
maintenance table.
The spark plugs can be serviced by opening the left and
rig
ht door panels.
Replace a spark plug when the following occurs:
• Spark plug is damaged/insulator is cracked or
missing
• Plug electrode/insulator is fouled
• Replace at interval in maintenance table
When inspecting a spark plug, take n
ote of the electrode
and insulator color. A light brown/dark tan color indicates
the engine is running properly.
If the spark plug electrode/insulator is white, the engine
may be
running lean. Inspect the engine, throttle body
boots, etc. for air leaks.
If the spark plug electrode/insulator
is black, oily, or shows
heavy soot, the engine may be running rich. Inspect the
engine, fuel system, and lubrication system for problems.
Set the electrode gap to specification
before installing a
new spark plug.
