Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool down before starting work.

2. Replace Fuel Filter

• Locate the fuel filter; typically found along the fuel line under the vehicle.
• Use a socket set to remove the mounting bolts.
• Disconnect the fuel lines from both ends of the filter, using a rag to catch any spilled fuel.
• Install the new fuel filter, ensuring correct orientation and secure connections.
• Reattach the mounting bolts and reconnect the battery terminal.

3. Replace Spark Plugs

• Remove the ignition coil cover if applicable, using a socket set.
• Disconnect the ignition coil connectors and remove the coils.
• Use a spark plug socket to remove the old spark plugs.
• Inspect the gap on new spark plugs and adjust if necessary.
• Install the new spark plugs and torque them to manufacturer specifications (typically around 13-15 lb-ft).
• Reinstall ignition coils and connectors.

4. Clean or Replace Air Filter

• Open the air intake housing using a screwdriver or socket set.
• Remove the old air filter and inspect for dirt or clogs.
• Install a new air filter or clean the existing one if reusable.
• Reassemble the air intake housing.

5. Inspect and Repair Vacuum Leaks
