Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Clean Throttle Body

Remove the air intake duct by loosening the clamps with a socket set.
Spray throttle body cleaner onto a clean rag and gently scrub the throttle plate and interior to remove carbon deposits.
Reinstall the air intake duct and secure it with the clamps.

3. Replace Air Filter

Locate the air filter housing, typically secured with clips or screws.
Open the housing and remove the old air filter.
Install a new air filter, ensuring it is seated properly.
Close the housing and secure it.

4. Check and Replace Fuel Filter

Locate the fuel filter along the fuel line (consult repair manual for specific location).
Relieve fuel system pressure before disconnecting the fuel lines.
Remove the old fuel filter using a wrench.
Install the new fuel filter in the correct orientation and reconnect the fuel lines securely.

5. Inspect and Clean MAF Sensor

Disconnect the electrical connector from the MAF sensor.
Remove the MAF sensor from the intake duct (may require a screwdriver).
Use MAF cleaner to spray the sensor and allow it to air dry before reinstalling.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes before test driving to ensure proper operation.
