Solution
1. Preparation
  • Gather all tools and parts required for the repair.
  • Disconnect the negative battery terminal to ensure safety while working on electrical components.
2. Replace Air Filter
  • Remove the air filter housing cover using a socket set.
  • Replace the old air filter with a new one, ensuring it fits snugly.
  • Reattach the air filter housing cover, securing it properly.
3. Fuel System Inspection and Repair
  • If fuel pressure is low, replace the fuel pump:
    • Drain the fuel tank to a manageable level.
    • Disconnect the fuel lines using a line wrench to prevent damage.
    • Remove the fuel pump assembly from the tank by unscrewing the retaining ring.
    • Install the new fuel pump and reassemble the components in reverse order.
  • Check and replace the fuel filter if clogged.
4. Spark Plug Inspection and Replacement
  • Remove the ignition coil packs using a socket set.
  • Extract the spark plugs with a spark plug socket.
  • Inspect the spark plugs for wear; replace with OEM or equivalent parts as necessary.
  • Reinstall the spark plugs and coil packs.
5. Throttle Position Sensor (TPS) Replacement
  • Locate the TPS on the throttle body.
  • Disconnect the electrical connector.
  • Remove the screws holding the TPS in place using a screwdriver.
  • Install the new TPS and reconnect the electrical connector.
6. Clean the Mass Air Flow (MAF) Sensor
  • Carefully remove the MAF sensor from the intake duct.
  • Use MAF sensor cleaner to spray the sensor elements; avoid touching them.
  • Allow to dry, then reinstall the MAF sensor securely.

Tools Required:

  • OBD-II scanner
  • Socket set
