Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent any electrical issues.
2. Inspect and Clean Air Intake System
  • Remove the air intake duct by loosening the clamps with a screwdriver.
  • Inspect the air filter; replace if dirty.
  • Clean the throttle body using throttle body cleaner and a soft cloth, paying special attention to the throttle plate.
3. Check and Replace Spark Plugs
  • Remove the ignition coils by unscrewing the bolts and disconnecting the wiring harness.
  • Unscrew and remove the old spark plugs using a spark plug socket.
  • Inspect the spark plugs for wear; replace with new ones if necessary, ensuring they are gapped according to manufacturer specifications.
4. Test and Replace Fuel Filter (if necessary)
  • Locate the fuel filter; check the manufacturer’s service manual for specific location.
  • Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
  • Disconnect fuel lines and replace the old filter with a new one, ensuring proper orientation.
5. Inspect and Clean Idle Air Control Valve (IAC)
  • Locate the IAC valve on the throttle body.
  • Remove the IAC valve by unscrewing it from the throttle body.
  • Clean the valve with appropriate cleaner and reattach it, ensuring a proper seal.
