Solution

1. Preparation

Gather all tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on the vehicle.

2. Address Air Intake Issues

Inspect and Replace Air Filter:
- Remove the air filter housing cover using a socket set.
- Check the air filter for dirt and debris. Replace it if necessary.
- Reassemble the air filter housing and ensure it is securely fastened.

3. Fuel System Repair

Check and Replace Fuel Filter:
- Locate the fuel filter (usually under the vehicle near the fuel tank).
- Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
- Disconnect fuel lines and remove the old fuel filter.
- Install the new fuel filter ensuring correct orientation and secure all connections.

4. Ignition System Maintenance

Inspect and Replace Spark Plugs:
- Remove the ignition coil cover if applicable.
- Disconnect the ignition coils and remove them using a socket set.
- Remove the spark plugs using a spark plug socket and inspect them for wear.
- Replace with new spark plugs (gapping them according to manufacturer specifications) and reinstall coils.

5. Exhaust System Inspection

Examine Catalytic Converter:
- Inspect the exhaust system for any visible damage or blockages.
- If a restriction is suspected, remove the catalytic converter and inspect it for clogging. Replace if necessary.
