Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft brush to clean the throttle body surfaces.
Reattach the air intake duct securely.

3. Check and Clean the MAF Sensor

Locate the MAF sensor along the air intake.
Disconnect the electrical connector and remove the sensor.
Clean the MAF sensor with MAF cleaner (do not use throttle cleaner).
Reinstall the sensor and reconnect the electrical connector.

4. Inspect Fuel System

Use a fuel pressure gauge to check the pressure at the fuel rail.
If pressure is below specifications, check the fuel pump and fuel filter for blockage or failure.
Replace the fuel filter if necessary and ensure the fuel pump functions properly.

5. Test Drive and Reset Systems

Reconnect the negative battery terminal.
Start the engine and allow it to warm up.
Perform a test drive to check for improvement in acceleration.
If any error codes were found and cleared earlier, verify that they do not return.
