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 (-). Standard value: 0.62? ± 10%
