Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the battery to prevent electrical shorts during repairs.
2. Inspect and Replace Spark Plugs
  • Remove the ignition coil or spark plug wires to access the spark plugs.
  • Use a spark plug socket and ratchet to remove the old spark plugs.
  • Inspect the spark plugs for wear; replace with new ones if necessary (use OEM specified type).
  • Torque new spark plugs to manufacturer's specifications (typically around 13-18 lb-ft).
3. Check and Replace Air Filter
  • Locate the air filter housing and remove the screws or clips securing it.
  • Take out the old air filter and inspect it for dirt and blockages.
  • Install a new air filter, ensuring it fits snugly in the housing.
  • Reattach the housing cover and secure it with screws or clips.
4. Fuel System Inspection
  • Locate the fuel pump access panel or remove the rear seat to access the fuel pump.
  • Use a fuel pressure gauge to check the fuel pressure against manufacturer's specifications.
  • If low, replace the fuel filter and inspect or replace the fuel pump if necessary.
5. Throttle Position Sensor (TPS) Adjustment
  • Locate the TPS on the throttle body and disconnect the electrical connector.
  • Use a multimeter to check the resistance across the TPS terminals while moving the throttle.
  • If readings are outside the specified range, replace the TPS and adjust it according to the manufacturer's specifications.
