Spark plug condition is indicative of engine operation. The spark plug
firing end condition should be read after the engine is warmed up and
the vehicle is driven at higher speeds. Immediately check the spark plug
for correct color. See page 70.
A hot exhaust system and engine can cause burns. Wear protective gloves
when removing a spark plug for inspection.
