  • Allow the engine to cool before starting work.
2. Clean or Replace Air Filter
  • Remove the air filter cover and inspect the filter.
    • Tools Required: Screwdriver, vacuum cleaner (if cleaning).
  • If clogged, replace with a new filter.
  • Reinstall the air filter cover securely.
3. Throttle Body Cleaning
  • Remove the throttle body from the intake manifold.
    • Tools Required: Socket set, torque wrench.
  • Use throttle body cleaner and a soft brush to clean the throttle plate and interior.
  • Reinstall the throttle body, ensuring it is torqued to manufacturer specifications.
4. Fuel Pressure Test
  • Connect a fuel pressure gauge to the fuel rail.
    • Tools Required: Fuel pressure gauge.
  • Turn the ignition to the "ON" position without starting the engine and check for pressure reading.
  • If the pressure is low, replace the fuel pump or fuel filter as necessary.
5. Inspect and Replace Spark Plugs
  • Remove the spark plug wires and use a socket to remove the spark plugs.
    • Tools Required: Spark plug socket, torque wrench.
  • Inspect for signs of wear or fouling; replace if necessary.
