Solution

1. Preparation

Gather tools and materials needed for the repair.
Disconnect the negative battery terminal to ensure safety during the process.
Allow the engine to cool before proceeding.

2. Address Diagnostic Codes

Sub-step 1: Use the OBD-II scanner to read and document any error codes.
Sub-step 2: Research and identify the specific issues related to the codes (e.g., misfire, O2 sensor failure).
Sub-step 3: Clear the codes and perform a test drive to see if they reappear.

3. Inspect and Clean the Throttle Body

Sub-step 1: Remove the air intake duct connected to the throttle body.
Sub-step 2: Use throttle body cleaner and a soft cloth to clean any carbon buildup on the throttle plate and bore.
Sub-step 3: Reinstall the air intake duct and ensure all clamps are secure.

4. Check and Replace Fuel Filter (if applicable)

Sub-step 1: Locate the fuel filter (check owner's manual for location).
Sub-step 2: Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Sub-step 3: Disconnect the fuel lines and remove the old fuel filter.
Sub-step 4: Install the new fuel filter and reconnect the fuel lines.

5. Replace Spark Plugs and Ignition Coils (if needed)

Sub-step 1: Remove the engine cover to access the spark plugs.
Sub-step 2: Use a socket and extension to remove the spark plugs, inspecting them for wear.
Sub-step 3: Replace with new spark plugs, ensuring correct torque specifications (typically around 15 lb-ft).
Sub-step 4: If ignition coils are faulty, remove and replace those as well.
