Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Address the Fuel System

Check Fuel Pump:
- Remove the fuel pump relay from the fuse box.
- Use a multimeter to test the fuel pump voltage while attempting to start the engine.
Replace Fuel Filter:
- Locate the fuel filter, usually near the fuel tank or along the fuel line.
- Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
- Disconnect fuel lines, ensuring to catch any spilled fuel.
- Replace the old filter with a new one, ensuring correct orientation.
- Reconnect fuel lines and the fuel pump relay.

3. Ignition System Maintenance

Inspect and Replace Spark Plugs:
- Remove the ignition coil covers using a socket set.
- Disconnect the ignition coil connectors and remove the coils.
- Use a spark plug socket to remove old spark plugs.
- Check the gap on new spark plugs and install them to factory specifications.
- Reinstall ignition coils and covers, ensuring all connections are secure.

4. Air Intake and Exhaust

Clean or Replace Air Filter:
- Locate the air filter housing and remove the cover.
- Remove the old air filter and clean the housing.
- Install a new air filter, ensuring a proper seal.
Inspect and Replace Catalytic Converter (if necessary):
- Check for back pressure in the exhaust system.
- If blocked, remove the exhaust system components as needed to access the catalytic converter.
- Replace with a new catalytic converter, ensuring all connections are tight and secure.
