Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety during repairs.
  • Allow the engine to cool completely before starting.
2. Inspect and Replace Fuel Filter
  1. Locate the fuel filter, typically situated along the fuel line.
  2. Use a socket set to remove the mounting brackets securing the fuel filter.
  3. Disconnect the fuel lines from the filter using a fuel line removal tool.
  4. Install the new fuel filter, ensuring the flow direction is correct.
  5. Reattach the fuel lines and secure the filter with mounting brackets.
3. Check and Replace Spark Plugs
  1. Remove the engine cover if applicable, using appropriate tools.
  2. Disconnect the ignition coils by pulling the connector off each coil.
  3. Use a spark plug socket to remove the old spark plugs.
  4. Inspect the old spark plugs for wear; replace them with new ones if necessary.
  5. Torque the new spark plugs to the manufacturer's specification (usually around 15-20 ft-lbs).
  6. Reconnect the ignition coils and replace the engine cover.
4. Test Throttle Position Sensor
  1. Locate the throttle position sensor, typically near the throttle body.
  2. Disconnect the electrical connector from the TPS.
  3. Using a multimeter, measure the resistance across the terminals of the TPS while moving the throttle plate.
  4. If readings are inconsistent or out of specification, replace the TPS.
  5. Reconnect the TPS connector.
