Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to ensure safety during work.
2. Clean or Replace Components

A. Clean Throttle Body

  1. Remove the air intake duct connected to the throttle body.
  2. Use throttle body cleaner and a soft brush to clean the throttle plate and bore.
  3. Reattach the air intake duct securely.

B. Replace Spark Plugs (if worn)

  1. Remove the ignition coil covers to access the spark plugs.
  2. Using a spark plug socket, carefully remove the old spark plugs.
  3. Inspect the gap on the new spark plugs and adjust if necessary to manufacturer's specifications.
  4. Install the new spark plugs and torque them to the manufacturer's specifications (typically around 13 lb-ft).
  5. Reinstall the ignition coil covers.

C. Inspect and Replace Fuel Filter (if necessary)

  1. Locate the fuel filter (if externally mounted) and relieve fuel system pressure.
  2. Disconnect fuel lines carefully using a fuel line removal tool.
