Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Fuel System Issues

Inspect the Fuel Pump:
- Remove the access panel (if applicable) to expose the fuel pump.
- Check the fuel pressure with a fuel pressure gauge.
- Replace the fuel pump if pressure is below manufacturer specifications.
Replace Fuel Filter:
- Locate the fuel filter and relieve the fuel system pressure.
- Disconnect the fuel lines and remove the old fuel filter.
- Install the new fuel filter, ensuring proper orientation, and reconnect the fuel lines.

3. Check and Replace Ignition Components

Inspect and Replace Spark Plugs:
- Remove the ignition coils to access the spark plugs.
- Inspect the spark plugs for wear or damage, and replace if necessary.
- Torque the new spark plugs to the manufacturer’s specifications.
Test and Replace Ignition Coils:
- Use a multimeter to test each ignition coil's resistance.
- Replace any faulty ignition coils.

4. Clean or Replace Air Filter

Remove the air filter from the air intake box.
Inspect for dirt or blockages.
Clean or replace the air filter as needed.

5. Inspect Exhaust System

Check for any visible damage or restrictions in the exhaust system.
If a clogged catalytic converter is suspected, perform a backpressure test and replace it if necessary.
