Removal and Installation
CAUTION: Spark plug wires must be connected correctly. Mark the spark plug wires before removing them from the spark plugs.
CAUTION: It is important to twist the spark plug wire boots while pulling upward to avoid possible damage to the spark plug wire.
NOTE: Loosen the spark plug one quarter turn then use compressed air to remove any foreign material in the spark plug well before removing the spark plugs.
NOTE: For flexible fuel (FF) vehicles, if an original spark plug is reused, make sure it is installed in the same cylinder from which it was taken. New spark plugs can be used in any cylinder.
