Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cooled down.
Disconnect the battery to prevent electrical shorts.

2. Scan and Interpret Codes

Use the OBD-II scanner to read the stored error codes.
Document all codes for reference during troubleshooting.

3. Inspect Ignition System

Remove the engine cover if necessary.
Check each spark plug for wear; replace if they appear burnt or fouled.
Test ignition coils with a multimeter; replace any faulty coils.

4. Examine Fuel System

Check fuel pressure using a fuel pressure gauge.
Replace the fuel filter if it is clogged or if fuel pressure is low.
Inspect fuel injectors for leaks or blockages; clean or replace as required.

5. Check Air Intake

Inspect the air filter for dirt or blockages; replace if necessary.
Check for any vacuum leaks in hoses connected to the intake manifold.

6. Final Assembly

Reconnect the battery once all components have been inspected or replaced.
Start the engine and monitor for any warning lights or abnormal sounds.
