Solution

1. Preparation

Ensure the vehicle is parked on a level surface with the engine off.
Gather necessary tools and safety equipment.
Disconnect the battery to prevent any electrical shocks.

2. Address Error Codes

Connect the OBD-II scanner and retrieve error codes.
Cross-reference codes with a repair manual to determine specific issues.
Clear the error codes and monitor if they return after a test drive.

3. Inspect and Replace Components

a. Engine Oil Inspection

Check oil level using the dipstick; add the manufacturer-recommended oil if low.
If oil is dirty or contaminated, perform an oil change.
- Remove the oil drain plug (use a socket set) and allow oil to drain completely.
- Replace the oil filter using an oil filter wrench.
- Reinstall the drain plug and refill with new oil to the correct level.

b. Spark Plug and Ignition Coil Replacement

Remove the engine cover (if applicable) using a socket set.
Disconnect the ignition coil connectors and remove the coils.
Replace worn spark plugs with new ones, ensuring proper gap settings.
Reinstall ignition coils and reconnect the connectors.

4. Fuel System Service

Check fuel pressure with a fuel pressure gauge; replace the fuel filter if pressure is low.
Inspect fuel injectors for proper operation; clean or replace as necessary.

5. Air Intake System Repair

Inspect the air filter for clogs and replace if necessary.
Check for vacuum leaks in hoses and connections; replace damaged hoses.
