Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace Spark Plugs

Remove the engine cover if necessary.
Use a spark plug socket to remove each spark plug.
Inspect for signs of wear and replace with OEM parts if damaged.
Torque new spark plugs to the manufacturer's specifications (usually around 15-20 Nm).

3. Test and Replace Ignition Coils

Remove the ignition coils from each spark plug.
Use a multimeter to check their resistance; replace any that are out of spec.
Reinstall new ignition coils, ensuring they click into place securely.

4. Check and Replace Fuel Filter

Locate the fuel filter (refer to the owner's manual for location).
Use a wrench to disconnect the fuel lines from the filter, ensuring to catch any spilled fuel.
Replace the old filter with a new OEM filter and reconnect the lines securely.

5. Inspect and Clean Air Intake

Remove the air filter cover and inspect the air filter for dirt and obstructions.
Clean the air intake hoses and throttle body with an appropriate cleaner.
Reinstall the air filter and cover.
