Solution

1. Preparation

Gather tools and parts needed for repairs.
Tools Required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, multimeter, cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Engine Codes

If error codes are found, repair or replace faulty components as indicated by the codes.
Clear codes from the OBD-II scanner and monitor if they reappear.

3. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt or damage.
Install a new air filter, ensuring it is seated properly.
Reattach the air filter housing cover and secure it.

4. Clean Fuel Injectors

Use a fuel injector cleaner kit.
Follow the kit's instructions to connect the cleaning solution to the fuel rail.
Run the engine according to the kit’s guidelines to clean the injectors.

5. Inspect and Repair MAF Sensor

Locate the MAF sensor on the air intake duct.
Disconnect the electrical connector.
Remove the sensor using a socket set.
Clean the sensor with MAF cleaner spray and let it dry.
Reinstall the sensor and reconnect the electrical connector.
