Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt and obstructions.
Replace the air filter with a new, OEM-quality part if dirty. Reassemble the air filter housing.

3. Check and Replace Fuel Filter

Locate the fuel filter (usually located along the fuel line).
Relieve fuel system pressure using the fuel pressure release valve.
Disconnect the fuel lines from the filter using appropriate line wrenches.
Replace the old fuel filter with a new one, ensuring the orientation matches the flow direction arrow on the filter.
Reconnect the fuel lines securely.

4. Inspect and Replace Ignition Components

Remove the engine cover to access the ignition coils.
Disconnect the electrical connectors from each ignition coil.
Remove the bolts securing the ignition coils and take them out.
Inspect the spark plugs for wear; replace them if necessary (torque to manufacturer specifications).
Install new ignition coils, ensuring they are securely fastened and connected.

5. Exhaust System Inspection

Visually inspect the exhaust system for dents, holes, or rust.
If any restrictions are found, consider replacing the affected sections of the exhaust or the catalytic converter.
