(7) Using a 16 mm (0.63 in.) plug wrench, install the spark plug.

(8) Install the 4 ignition coils with the 4 bolts and connect the 4 ignition coil connectors. Torque: 9.0 N*m (92 kgf*cm, 80 in.*lbf)

(9) Connect the 4 fuel injector connectors.

(10) Install the No. 1 engine cover.

2. CHECK SPARK PLUG

(a) Check the electrode.

(1) Using a megohmmeter, measure the insulation resistance.

Standard insulation resistance: 10 MQ or more

HINT:

• If a megohmmeter is not available, perform the following simple inspection instead.

• If the result is 10 MQ or less, clean the plug and measure the resistance again.

(b) Alternative inspection method:

(1) Quickly accelerate the engine to 4,000 rpm 5 times.

(2) Remove the spark plug.

(3) Visually check the spark plug.

If the electrode is dry, the spark plug is functioning properly. If the electrode is damp, proceed to the next step.

(c) Check the spark plug for any damage to its threads and insulator.

If there is damage, replace the spark plug. Recommended spark plug

(d) Check the spark plug electrode gap.

Maximum electrode gap for used spark plug: 1.3 mm (0.051 in.)

If the gap is greater than the maximum, replace the spark plug.

Electrode gap for new spark plug: 1.0 to 1.1 mm (0.039 to 0.043 in.)
