Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Addressing Engine Codes

Use the OBD-II scanner to check for and document any fault codes.
Clear the error codes and take the vehicle for a test drive to see if they return.

3. Inspect and Replace the Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and check for dirt or damage.
Install a new OEM air filter, ensuring it fits snugly.
Reattach the air filter housing cover securely.

4. Fuel System Inspection

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start) to check pressure readings.
If the pressure is below specifications, inspect the fuel pump and replace if necessary.
Replace the fuel filter if it shows signs of clogging.

5. Throttle Body Cleaning

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Check for proper operation by manually moving the throttle plate.
Reassemble the intake duct securely.
