Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, basic hand tools
Disconnect the negative battery terminal to prevent electrical shock.

2. Replace Faulty Spark Plugs and Ignition Coils

Remove the engine cover (if applicable) using a socket set.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils by unscrewing them from the engine.
Replace the spark plugs using a spark plug socket; ensure to gap them according to manufacturer specifications.
Reinstall the ignition coils and reconnect the electrical connectors.
Reattach the engine cover.

3. Replace the Air Filter

Locate the air intake housing and remove the clips or screws securing it.
Take out the old air filter and inspect the housing for debris.
Install the new air filter, ensuring it is seated properly.
Reattach the air intake housing securely.

4. Clean Fuel System (if necessary)

Add a fuel system cleaner to the gas tank as per manufacturer instructions.
Run the engine for at least 30 minutes to allow the cleaner to circulate through the system.

5. Test Drive and Monitor Performance

Reconnect the negative battery terminal.
Start the engine and let it idle for a few minutes.
Perform a test drive to monitor for improvements in power and acceleration.
