Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool if it has been recently running.

2. Addressing Fuel Delivery Issues

Fuel Pump Inspection:
- Locate the fuel pump access panel (if applicable) and remove it.
- Check the fuel pump relay and fuse for continuity.
- Use a fuel pressure gauge to test fuel pressure; compare readings to manufacturer specifications.
Replace Fuel Filter:
- Disconnect the fuel lines using appropriate line wrenches.
- Remove the old fuel filter and install a new one, ensuring proper orientation.
- Reconnect fuel lines securely.

3. Inspecting the Ignition System

Spark Plug Replacement:
- Remove the ignition coil by unscrewing the bolts and disconnecting the electrical connector.
- Extract the spark plugs using a spark plug socket; inspect for wear or fouling.
- Install new spark plugs, torque to manufacturer's specifications (typically around 13 ft-lbs).
Coil Pack Inspection:
- Test each ignition coil with a multimeter for proper resistance.
- Replace any faulty coils.

4. Cleaning the Throttle Body

Remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft brush to clean carbon deposits.
Reinstall the throttle body with new gaskets, tightening to manufacturer specifications.
