Ignition Coil Inspection
- Perform the spark test and identify the malfunctioning cylinder. (See ENGINE CONTROL SYSTEM OPERATION INSPECTION .)
- Replace the ignition coil of the malfunctioning cylinder with that of a normal cylinder, and perform the spark test again. (See ENGINE CONTROL SYSTEM OPERATION INSPECTION
.)
- If the spark is not normal due to a malfunctioning ignition coil, replace that ignition coil.
- It is unlikely that all four ignition coils fail to operate properly. To prevent replacing a normal component, perform the above procedure, identify the malfunctioning ignition coil, and replace it.
