Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Address Fuel Delivery Issues

Check Fuel Pump:
- Locate and access the fuel pump (typically found in the fuel tank).
- Test the fuel pump relay and fuses for continuity.
- Replace the fuel pump if it fails to meet pressure specifications.
Replace Fuel Filter:
- Locate the fuel filter (often along the fuel line).
- Disconnect the fuel lines using a wrench.
- Remove and replace the old fuel filter, ensuring correct orientation.
- Reconnect the fuel lines securely.

3. Inspect and Replace Ignition Components

Inspect Spark Plugs:
- Remove spark plug wires or coils.
- Extract the spark plugs using a spark plug socket.
- Check for wear, carbon buildup, or damage; replace if necessary.
Test Ignition Coils:
- Use a multimeter to test the primary and secondary resistance of coils.
- Replace any faulty ignition coils.

4. Address Air Intake Issues

Replace Air Filter:
- Locate the air filter housing and open it.
- Remove the old air filter and clean the housing as needed.
- Install a new air filter that meets OEM specifications.

5. Check for Vacuum Leaks

Inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses and ensure all connections are secure.
