Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Extract the air filter and inspect for dirt or damage.
If dirty, clean it with compressed air or replace it with a new OEM air filter.
Reassemble the air filter housing cover.

3. Fuel System Inspection

Locate the fuel pressure test port on the fuel rail.
Attach a fuel pressure gauge to the test port.
Turn the ignition to the "ON" position (do not start the engine) and read the fuel pressure.
- If pressure is below specifications (typically around 30-50 psi), consider replacing the fuel pump or filter.
Disconnect the gauge and securely reconnect the fuel line.

4. Throttle Body Cleaning

Locate the throttle body and remove the intake duct using a socket set.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Pay special attention to the throttle plate and surrounding areas.
Reinstall the intake duct securely.

5. MAF Sensor Inspection

Locate the MAF sensor in the intake duct.
Disconnect the electrical connector and remove the sensor using a Torx screwdriver.
Clean the sensor with MAF cleaner spray (do not touch the sensor elements).
Reinstall the MAF sensor and connector.

6. Exhaust System Inspection

Visually inspect the exhaust system for any signs of blockage or damage.
If there are signs of damage, repair or replace the affected components (e.g., catalytic converter).
