Installation
   
Do not confuse the ignition coil #2 with #4 connections.
Doing so may cause the engine to stall due to incomplete ignition. And, since unburned fuel flows into the catalyst, this can overheat and damage the catalyst.
A yellow tag (A) is attached to ignition coil #4. Use this tag for reference when connecting the ignition coils.

1.
Install in the reverse order of removal.

Ignition coil installation bolts:
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 Ib-ft)

Inspection
1.
Measure the primary coil resistance between terminals (+) and (-).
