6 CHANGE NORMAL SPARK PLUG AND CHECK SPARK OF MISFIRING CYLINDER
(a) Change the spark plug with the normal spark plug.
(b) Perform a spark test.
CAUTION:
Completely disconnect each injector connector.
NOTICE:
Do not crank the engine for more than 5 to 10 seconds.
(1) Install the spark plug to the ignition coil, and connect the ignition coil connector.
(2) Disconnect the injector connector.
(3) Ground the spark plug.
(4) Check if a spark occurs while the engine is being cranked.
OK: A spark jumps across electrode gap.
