Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery for safety.
Allow the engine to cool before starting work.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any error codes.
Clear the codes and perform a test drive to see if they return.

3. Engine Oil Change (if necessary)

Remove the engine oil drain plug using a socket wrench and let old oil drain completely.
Replace the drain plug and torque it to manufacturer specifications (typically around 25-30 ft-lbs).
Replace the oil filter using an oil filter wrench.
Fill the engine with the recommended oil type (usually 5W-30 or as per owner's manual).

4. Air Filter Replacement (if necessary)

Locate the air filter housing and remove it by unscrewing or unclipping it.
Take out the old air filter and replace it with a new one, ensuring it fits snugly.
Reattach the housing securely.

5. Fuel System Inspection

Inspect fuel lines for any visible leaks or damage.
If fuel injectors are suspected, consider cleaning or replacing them.
Ensure the fuel pump is operating correctly by checking pressure with a fuel gauge.

6. Exhaust System Check

Visually inspect the exhaust system for cracks or holes, especially around the catalytic converter.
Replace any damaged components as necessary.
