Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools and parts needed for the repair.
Wear appropriate safety gear (gloves, safety glasses).

2. Address Engine Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note the trouble codes.
Research codes to determine specific faults and required repairs.

3. Inspect and Replace Spark Plugs

Remove the engine cover if applicable.
Disconnect the ignition coils from the spark plugs.
Use a spark plug socket to remove and inspect spark plugs.
- If worn or damaged, replace with OEM specifications.
Reinstall new spark plugs and reconnect ignition coils.

4. Check and Replace Ignition Coils (if needed)

If diagnostic codes indicate ignition coil issues, remove and replace faulty coils.
Disconnect the electrical connectors and remove the bolts securing the coils.
Install new coils and reconnect electrical connectors.

5. Inspect Fuel System

Check fuel pressure using a fuel pressure gauge.
If pressure is low, inspect the fuel pump and fuel filter for blockage or failure.
Replace the fuel filter if necessary and ensure the pump operates correctly.

6. Verify Air Intake System

Inspect the air filter and replace if dirty.
Check for vacuum leaks in hoses connected to the intake manifold.
Ensure the throttle body is clean and functioning properly.
