Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.
Allow the engine to cool before starting repairs.

2. Inspect and Replace Spark Plugs

Remove the engine cover if necessary.
Disconnect the ignition coils from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect the spark plugs for damage or excessive wear.
Install new spark plugs, ensuring they are torqued to the manufacturer's specifications (typically 15-20 lb-ft).
Reconnect the ignition coils.

3. Test and Replace Ignition Coils (if necessary)

If the ignition coils were found to be faulty in the diagnostic steps, remove the old coils.
Install new ignition coils, ensuring they are seated properly.
Reconnect electrical connectors to the coils.

4. Inspect and Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
Ensure the throttle plate moves freely and is not sticking.

5. Check Fuel System

Test the fuel pressure using a fuel pressure gauge to ensure it meets specifications.
If low, inspect the fuel pump and replace it if necessary.
Check the fuel filter and replace it if clogged.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any stored trouble codes.
Start the engine and observe for any abnormal operation.
