Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the battery to ensure safety while working on the vehicle.
  • Allow the engine to cool before starting repairs.
2. Address Fuel Delivery Issues

  1. Fuel Pressure Check

    • Connect a fuel pressure gauge to the fuel rail.
    • Start the engine and check if the pressure meets manufacturer specifications (usually around 3-5 bar).
    • If pressure is low, replace the fuel pump or check for clogged fuel filters.

  2. Replace Fuel Filter (if necessary)

    • Locate the fuel filter (typically near the fuel tank or along the fuel line).
    • Use proper tools to remove and replace the filter, ensuring the correct orientation for fuel flow.
3. Inspect and Replace Spark Plugs

  1. Remove Ignition Coils

    • Disconnect the electrical connector from each ignition coil.
    • Remove the bolts securing the coils and gently pull them out.

  2. Replace Spark Plugs

    • Use a spark plug socket to remove old spark plugs.
    • Check spark plug gap and replace with new ones if necessary, ensuring the correct torque (usually around 20 Nm).
4. Clean or Replace Air Filter

  1. Inspect Air Filter

    • Open the air filter housing and remove the filter.
    • Inspect for dirt or blockages; clean or replace as needed.

  2. Reassemble Air Intake

    • Reinstall the air filter and close the housing securely.
5. Check and Adjust Throttle Position Sensor (TPS)

  1. Inspect TPS

    • Locate the TPS on the throttle body.
    • Disconnect the wiring harness and check voltage using a multimeter (consult specifications for correct voltage).

  2. Replace if Faulty

    • If no proper voltage is detected, remove the TPS and install a new one, ensuring correct alignment.
