Solution
1. Preparation
  • Gather tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the negative battery cable to prevent electrical shorts.

Tools Required:

  • OBD-II scanner
  • Fuel pressure gauge
  • Socket set
  • Multimeter
  • Screwdrivers
  • Torque wrench
2. Fuel System Inspection
  • Check Fuel Pressure

    • Attach the fuel pressure gauge to the fuel rail test port.
    • Start the engine and observe the pressure reading. It should match manufacturer specifications (typically around 40-50 psi for most Toyota models).
    • If the pressure is low, inspect the fuel pump relay and wiring.
  • Replace Fuel Filter (if applicable)

    • Locate and remove the fuel filter.
    • Install the new filter, ensuring the arrow on the filter points in the direction of fuel flow.
    • Reconnect fuel lines and check for leaks.
3. Air Intake System Cleaning
  • Clean Throttle Body

    • Remove the air intake duct connected to the throttle body.
    • Use throttle body cleaner and a soft cloth to clean the throttle plate and inside the throttle body.
    • Reattach the duct securely.
  • Replace Air Filter

    • Locate the air filter housing and remove the cover.
    • Replace the old air filter with a new one, ensuring it is seated properly.
4. Sensor Testing and Replacement
  • Test and Replace MAF Sensor
    • Disconnect the MAF sensor electrical connector.
    • Use a multimeter to check for voltage output while the engine is running.
    • If readings are out of specification, replace the MAF sensor.
5. Exhaust System Check
  • Inspect Catalytic Converter
    • Visually inspect for damage or signs of clogging.
    • If necessary, perform a backpressure test to determine if the catalytic converter is functioning correctly.
    • Replace if backpressure exceeds manufacturer specifications.
