Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to prevent any electrical shorts.

2. Fuel System Inspection

Check Fuel Pump:
- Locate the fuel pump access panel (if applicable).
- Connect a fuel pressure gauge to the fuel line.
- Turn the ignition to the "ON" position (without starting the engine) and check for the correct fuel pressure (typically 30-50 PSI).
- If pressure is low, replace the fuel pump.
Replace Fuel Filter:
- Locate the fuel filter (if serviceable) and prepare a container to catch any fuel.
- Disconnect the fuel lines from the filter using appropriate wrenches.
- Install the new fuel filter, ensuring proper orientation and securing the lines.

3. Air Intake System Cleaning

Throttle Body Cleaning:
- Remove the throttle body from the intake manifold (ensure to label connections).
- Use throttle body cleaner and a soft cloth to clean the interior surfaces.
- Reinstall the throttle body and reconnect all wiring and hoses.

4. Ignition System Service

Inspect/Replace Spark Plugs:
- Remove the spark plug wires or ignition coils.
- Use a spark plug socket to remove the spark plugs.
- Inspect for wear or damage and replace if necessary, ensuring to gap them to manufacturer specifications.
Check Ignition Coils:
- Test each ignition coil with a multimeter for proper resistance.
- Replace any faulty coils as needed.
