Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety while working on the vehicle.
2. Replace Spark Plugs
  • Remove the engine cover if applicable.
  • Use a socket set to unscrew and remove the old spark plugs.
  • Inspect the old plugs for signs of wear or fouling.
  • Install new spark plugs, ensuring they are gapped correctly (typically 0.044 inches for Honda CR-V).
  • Torque the spark plugs to the manufacturer’s specifications (usually 13 lb-ft).
3. Clean the Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle body and the throttle plate.
  • Ensure there is no residue left behind.
  • Reattach the air intake duct securely.
4. Inspect and Replace Fuel Filter (if applicable)
  • Locate the fuel filter, which is usually along the fuel line under the vehicle.
  • Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
  • Disconnect fuel lines carefully and replace the old fuel filter with a new one, ensuring proper orientation.
  • Reconnect the fuel lines and replace the fuel pump fuse.
5. Reconnect Battery and Test
  • Reconnect the battery terminals.
  • Start the vehicle and allow it to idle.
  • Monitor for any unusual sounds or vibrations.
