  • OBD-II scanner
  • Fuel pressure gauge
  • Screwdrivers and socket set
  • Torque wrench
  • Cleaning supplies (MAF cleaner, throttle body cleaner)
  • Inspection mirror
  • Multimeter
Repair Instructions

Step 1: Clean or Replace Air Filter

  1. Open the hood and locate the air filter housing.
  2. Remove the clips or screws and take out the air filter.
  3. Inspect the air filter; if dirty, replace it with a new one.

Step 2: Clean MAF Sensor

  1. Disconnect the electrical connector from the MAF sensor.
  2. Remove the sensor from its housing.
  3. Spray MAF cleaner on the sensor element and allow it to dry before reinstallation.

Step 3: Check and Clean Throttle Body

  1. Remove the intake duct to access the throttle body.
  2. Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
  3. Reconnect the intake duct securely.

Step 4: Inspect and Replace Fuel Filter (if necessary)

  1. Locate the fuel filter, usually near the fuel tank or along the fuel line.
  2. Depressurize the fuel system by removing the fuel pump fuse and starting the engine until it stalls.
  3. Disconnect the fuel lines from the old filter and install the new filter in the correct orientation.

Step 5: Check and Replace Spark Plugs

  1. Remove the spark plug wires or ignition coils (whichever applies).
  2. Use a spark plug socket to remove the spark plugs.
  3. Inspect and replace any worn spark plugs with OEM-spec replacements.

Step 6: Transmission Fluid Check/Change

  1. If the fluid level is low, add the recommended transmission fluid.
  2. Consider a complete transmission fluid change if the fluid is dark or smells burnt.

Step 7: Clear Codes and Test Drive

  1. Clear any DTCs using the OBD-II scanner.
  2. Take the vehicle for a test drive to ensure the acceleration issue is resolved.
Conclusion

If the problem persists after performing these checks and repairs, further diagnostics are required, possibly involving deeper inspection of the ECU and transmission. If necessary, consult with a professional technician or a Toyota dealership for advanced troubleshooting and repair.
