Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for misfire codes.
2
Inspect the condition of the spark plugs visually; remove the ignition coils for access.
3
Measure spark plug gap with a feeler gauge to ensure it meets specifications.
4

Solution

1. Preparation

Tools Required: Socket set, torque wrench, ratchet, extension, spark plug gap tool, dielectric grease, vacuum cleaner (optional for cleaning).
Ensure the engine is cool before starting work.
Disconnect the negative terminal of the battery to avoid electric shock.

2. Remove Engine Cover

Unscrew any bolts or fasteners holding the engine cover in place using a socket set.
Carefully lift off the engine cover and set it aside.

3. Remove Ignition Coils

Identify the ignition coils; they are located on top of the spark plugs.
Disconnect the electrical connectors on each ignition coil by pressing the tab and pulling them out.
Unscrew the bolts securing the ignition coils using a socket set.
Pull out the ignition coils carefully to avoid damaging them.

4. Remove Old Spark Plugs

Use a spark plug socket and ratchet to unscrew the old spark plugs from the engine.
Carefully pull the spark plugs out, ensuring no debris falls into the combustion chamber.

5. Install New Spark Plugs

Check the gap on the new spark plugs using a feeler gauge; adjust if necessary to match manufacturer specifications.
Apply a small amount of dielectric grease to the threads of the new spark plugs to facilitate future removal.
Carefully thread the new spark plugs into the cylinder head by hand, then tighten with a torque wrench to the manufacturer’s specified torque setting (typically around 22-30 Nm).

6. Reinstall Ignition Coils

Place the ignition coils back over the new spark plugs.
Secure them with the bolts removed earlier and reconnect the electrical connectors until they click into place.

7. Replace Engine Cover

Position the engine cover back in place and secure it with the bolts.

8. Reconnect Battery

Reconnect the negative terminal of the battery.
