Solution

1. Preparation

Gather tools and materials needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Address Fault Codes

Sub-step 1: Note the error codes retrieved from the OBD-II scanner.
Sub-step 2: Research the fault codes to determine the associated components that may need inspection or replacement.

3. Replace Spark Plugs (if faulty)

Sub-step 1: Remove the engine cover if applicable by unscrewing the bolts.
Sub-step 2: Disconnect the ignition coils from the spark plugs.
Sub-step 3: Remove old spark plugs using a spark plug socket and ratchet.
Sub-step 4: Install new spark plugs, ensuring they are gapped correctly according to manufacturer specifications (typically around 0.028-0.032 inches).
Sub-step 5: Reattach the ignition coils and engine cover.

4. Clean or Replace Air Filter

Sub-step 1: Open the air filter housing by unclipping or unscrewing it.
Sub-step 2: Remove the old air filter and inspect for dirt and debris.
Sub-step 3: If cleaning, use compressed air to blow out dust; otherwise, install a new air filter.
Sub-step 4: Reassemble the air filter housing securely.

5. Inspect and Clean Fuel Injectors

Sub-step 1: Remove the fuel rail according to the service manual instructions.
Sub-step 2: Take out the fuel injectors and inspect for clogs or leaks.
Sub-step 3: Clean injectors using a specialized cleaner or replace them if necessary.
Sub-step 4: Reinstall the fuel injectors and fuel rail, ensuring all connections are secure.

6. Recheck Engine Oil

Sub-step 1: Check the engine oil level using the dipstick.
Sub-step 2: If low or dirty, drain the old oil and replace it with the recommended oil type and quantity.
Sub-step 3: Install a new oil filter if necessary.
