Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety during the repair.

2. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reconnect the air intake duct securely.

3. Inspect and Replace Air Filter

Locate the air filter housing and open it.
Remove the old air filter and inspect it for dirt and clogs.
Install a new air filter that meets OEM specifications.

4. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter along the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter and replace it with a new one, ensuring proper orientation.

5. Inspect and Clean MAF Sensor

Locate the MAF sensor in the air intake system.
Remove it carefully and use MAF cleaner to spray the sensor elements gently.
Allow it to dry completely before reinstalling.
