Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety during repairs.
2. Inspect and Replace the Throttle Position Sensor (TPS)
  • Locate the TPS on the throttle body.
  • Disconnect the electrical connector from the TPS.
  • Remove the TPS using a socket set (typically 10mm).
  • Install the new TPS by aligning it correctly and securing it with the screws.
  • Reconnect the electrical connector.
3. Address Fuel System Issues
  • If the fuel pressure was low during diagnostic steps, replace the fuel filter.
    • Locate the fuel filter (typically under the car along the fuel line).
    • Relieve fuel system pressure by removing the fuel pump fuse, starting the engine, and letting it stall.
    • Disconnect the fuel lines and remove the old filter.
    • Install the new filter, ensuring the flow direction is correct.
  • If the fuel pump is faulty, replace it by accessing it through the fuel tank or rear seat, depending on the model.
4. Check for Exhaust Blockages
  • Inspect the exhaust system visually for any obvious signs of damage or obstruction.
  • If the catalytic converter is suspected to be blocked, use a backpressure gauge to verify.
  • If confirmed, replace the catalytic converter according to manufacturer's specifications.
