Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety during electrical repairs.

2. Addressing Fuel System Issues

Inspect Fuel Pump:
- Locate the fuel pump (usually in the fuel tank).
- Test fuel pressure with a fuel pressure gauge; it should meet factory specifications (check service manual).
- If pressure is low, consider replacing the fuel pump.
Replace Fuel Filter:
- Locate the fuel filter along the fuel line.
- Relieve fuel system pressure, then disconnect the fuel lines.
- Remove the old fuel filter and install a new one, ensuring proper orientation.

3. Inspecting and Cleaning the Throttle Body

Remove Throttle Body:
- Disconnect electrical connectors and any vacuum hoses attached to the throttle body.
- Remove the throttle body mounting bolts using the appropriate socket.
- Carefully remove the throttle body from the intake manifold.
Clean Throttle Body:
- Use throttle body cleaner and a soft cloth to clean the throttle plate and interior surfaces.
- Ensure no cleaner residue remains. Allow it to dry completely before reinstallation.

4. Ignition System Check

Inspect Spark Plugs:
- Remove spark plug wires and use a socket to remove the spark plugs.
- Check for wear, carbon buildup, or damage; replace if necessary.
Replace Ignition Coils (if needed):
- Remove the ignition coil from its mounting and disconnect the electrical connector.
- Install new ignition coils, ensuring they are seated properly.

5. Reassembly

Reinstall the throttle body and ensure all connections are secure.
Reconnect battery terminal and ensure tight connections.
Start the engine and allow it to idle to ensure everything is operating correctly.
