Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Ignition Components

Tools Required: Socket set, torque wrench, spark plug socket.
Remove the engine cover if applicable.
Unclip and remove the ignition coils from the spark plugs.
Inspect the spark plugs for wear; replace if necessary (check gap specifications).
Reinstall new spark plugs and torque to manufacturer specifications (typically around 13 lb-ft).
Reattach ignition coils and ensure they are secured properly.

3. Check and Clean Fuel Injectors

Tools Required: Fuel injector cleaning kit, fuel pressure gauge.
Disconnect the fuel supply line and relieve fuel pressure.
Remove the fuel injectors from the intake manifold.
Use a fuel injector cleaning kit to clean the injectors or replace them if they are faulty.
Reinstall the injectors and ensure all connections are secure.

4. Inspect Air Intake System

Tools Required: Screwdrivers, vacuum gauge.
Remove the air intake duct and inspect for debris or blockages.
Check the air filter and replace if clogged.
Inspect for any vacuum leaks using a vacuum gauge and repair as necessary.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any error codes.
Start the engine and ensure the check engine light remains off.
