Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative terminal of the battery to prevent any electrical shorts.
2. Inspect Spark Plugs
  • Remove the ignition coil cover using a socket set.
  • Unscrew the spark plugs using a spark plug socket.
  • Inspect each spark plug for wear or deposits. Replace if necessary.
3. Clean or Replace Fuel Injectors
  • Use a fuel injector cleaning kit or replace the injectors if they are damaged.
  • If cleaning, remove the fuel rail (be cautious of fuel pressure).
  • Follow kit instructions or reinstallation steps for injectors.
4. Check and Clean MAF Sensor
  • Disconnect the MAF sensor connector.
  • Remove the sensor using a Torx screwdriver.
  • Clean the sensor with MAF cleaner; do not touch the sensing element.
  • Reinstall the sensor and reconnect the connector.
5. Test Throttle Position Sensor
  • Disconnect the TPS connector.
  • Use a multimeter to measure the resistance across the terminals.
  • Compare readings to specifications in the service manual. Replace if out of spec.
6. Reassemble and Test
  • Reinstall all components removed during the process.
  • Reconnect the battery terminal.
  • Start the engine and check for smooth idle and absence of the check engine light.
