Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety during repairs.
2. Inspect and Replace Air Filter
  • Remove the air filter cover using a socket set.
  • Take out the old air filter and inspect it for dirt or blockage.
  • Replace with a new OEM air filter.
  • Reassemble the air filter cover and ensure it is secured properly.
3. Check and Replace Fuel Pump (if necessary)
  • Remove the rear seat or access panel to reach the fuel pump.
  • Disconnect the electrical connector and fuel lines (use safety goggles and rags to catch any spills).
  • Unscrew the fuel pump assembly and remove it.
  • Install the new fuel pump, ensuring it is seated correctly and reconnect all lines.
  • Reconnect the battery.
4. Test Throttle Position Sensor
  • Locate the throttle body and disconnect the TPS connector.
  • Using a multimeter, check the voltage output of the TPS while manually moving the throttle plate.
  • If readings are outside manufacturer specifications, replace the TPS.
5. Inspect and Replace Spark Plugs and Ignition Coils
  • Remove the engine cover (if applicable) using the socket set.
  • Remove the ignition coil bolts and disconnect the coils from the spark plugs.
  • Replace spark plugs with the correct type and torque them to specification.
  • Reinstall ignition coils and secure them with bolts.
