Solution

1. Preparation

Gather tools and materials:
- OBD-II scanner
- Socket set
- Torque wrench
- Screwdrivers
Ensure the vehicle is on a level surface and the engine is cool.

2. Scan and Identify Fault Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition key to the "On" position without starting the engine.
Record any fault codes and refer to a repair manual for troubleshooting.

3. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable) using a socket set.
Disconnect the electrical connectors from the ignition coils.
Remove the spark plugs using a spark plug socket and inspect for wear.
Replace any worn or damaged spark plugs with new ones, ensuring proper gap is set.

4. Check and Replace Ignition Coils

If codes indicate issues with ignition coils, remove the affected coils by unscrewing and gently pulling them out.
Install new ignition coils, ensuring they are seated properly and reconnect the electrical connectors.

5. Inspect Fuel Injectors

Check for power to the fuel injectors using a multimeter.
If injectors are clogged, remove them and clean or replace as necessary.

6. Verify Air Intake and Vacuum System

Inspect the air filter for blockages and replace if dirty.
Check all hoses for cracks or disconnections; replace any damaged hoses.
