4. Remove the engine cover. You will need to remove two 10 mm bolts to remove the engine cover.
5. Disconnect Ignition Coil. Unplug the electrical connector from the ignition coil. Press the small tab, then pull.
6. Do this for the rest of the ignition coils. 
7. You will need to remove the intake manifold to replace the back coils on this particular Nissan engine.
8. Remove Bolts. Remove the 10mm bolts that secure the coil in place.

Symptoms

What you may notice when a Nissan ignition coil fails:

• Check Engine Light On
• Engine misfiring
• Catalytic Converter Glowing Red
• Rough Idle
• Loss of power
• The car will not start or dies when idle.
• Engine shaking

While it is recommended to replace all the coils at the same time whenever possible, replacing only the faulty coil is an acceptable solution. If the coil is replaced with the same brand as the remaining coils, you shouldn’t notice any performance issues when only one coil is replaced.

Check Engine Light Still On

If the check engine light is still on after replacing the ignition coil, you can use the YOUCANIC Full System Scanner to clear the stored codes on your Nissan vehicle. This scanner also can read and clear fault codes on every control module of your vehicle.
