1. Preparation

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

2. Replace Air Filter

Remove the air filter cover using a socket set.
Take out the old air filter and check for dirt or blockages.
Install a new, clean air filter, ensuring it fits securely.
Reattach the air filter cover and tighten the screws.

3. Clean or Replace Fuel Injectors

If cleaning, use an appropriate fuel injector cleaner and follow the manufacturer's instructions.
If replacement is necessary, disconnect the fuel supply line and remove the injectors using a socket set.
Install new injectors, ensuring they are seated properly and reconnect the fuel line.

4. Replace MAF Sensor (if faulty)

Disconnect the electrical connector from the MAF sensor.
Unscrew the sensor from the air intake duct.
Install the new MAF sensor and reconnect the electrical connector.

5. Check and Adjust Tire Pressure
