Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety during repairs.
Ensure the work area is clean and organized.

2. Addressing Fuel System Issues

Fuel Filter Replacement
1. Locate the fuel filter (consult service manual for specific location).
2. Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
3. Disconnect the fuel lines using a line removal tool.
4. Replace the old fuel filter with a new one, ensuring proper orientation.
5. Reconnect the fuel lines and install the fuel pump relay.
Fuel Injector Cleaning
1. Remove the fuel injectors from the engine (consult service manual for specific instructions).
2. Use an injector cleaning kit or ultrasonic cleaner to clean each injector.
3. Reinstall the cleaned injectors, ensuring proper sealing.

3. Ignition System Repair

Spark Plug Replacement
1. Remove the ignition coils by unscrewing them from the cylinder head.
2. Unplug the electrical connectors from each coil.
3. Remove the spark plugs using a spark plug socket.
4. Install new spark plugs, ensuring the correct torque specification (typically around 13 lb-ft).
5. Reinstall the ignition coils and reconnect the electrical connectors.

4. Throttle Body Cleaning

Disconnect the throttle body from the intake manifold (remove any hoses or electrical connectors).
Use throttle body cleaner and a soft brush to clean the intake side of the throttle body.
Ensure the throttle plate can move freely and is not obstructed.
Reinstall the throttle body, ensuring all connections are secure.
