Solution
1. Preparation
  • Gather tools and parts needed for repair.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Clean or Replace Air Filter
  • Remove the air filter housing cover using a socket set.
  • Inspect the air filter; if dirty, clean it with compressed air or replace it.
  • Reassemble the air filter housing securely.
3. Inspect and Replace Spark Plugs
  • Remove the ignition coil using a socket and ratchet.
  • Extract the spark plug using a spark plug socket and extension.
  • Inspect for wear; replace with OEM spark plugs if necessary.
  • Reinstall the spark plug and ignition coil, tightening to the manufacturer's specified torque (typically around 13-15 lb-ft).
4. Clean Throttle Body
  • Remove the throttle body by disconnecting the electrical connectors and the intake hose.
  • Use a throttle body cleaner and a soft cloth or brush to clean the throttle plate and body.
  • Reinstall the throttle body, ensuring proper sealing and connections.
5. Test and Clean Fuel Injectors
  • If injectors are suspected, use a fuel injector cleaner or ultrasonic cleaning service.
  • Reinstall injectors according to specifications, ensuring O-rings are intact.
