Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down before starting work.

2. Address Error Codes

Use the OBD-II scanner to retrieve and document error codes.
Clear the codes and test drive the vehicle to see if they return.

3. Clean the Throttle Body

Tools Required: Socket set, throttle body cleaner, rags.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a rag to clean the throttle plate and surrounding areas.
Reattach the air intake duct securely.

4. Inspect and Clean the Mass Airflow Sensor

Tools Required: Screwdriver set, MAF cleaner.
Disconnect the MAF sensor connector and unscrew it from the air intake.
Spray MAF cleaner on the sensor and allow it to dry completely.
Reinstall the sensor and reconnect the connector.

5. Check Fuel System

Tools Required: Fuel pressure gauge.
Locate the fuel rail and attach the fuel pressure gauge.
Turn the ignition to the "ON" position (without starting) to check for fuel pressure.
If pressure is low, inspect the fuel pump and filter for issues.

6. Inspect Transmission Fluid

Tools Required: Transmission fluid dipstick.
Locate the transmission fluid dipstick and check the fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.
