Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to avoid electrical shorts.
Allow the engine to cool before working on components.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits snugly in the housing.
Reattach the housing cover and secure it.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
Wipe away any residue with a clean cloth.
Reinstall the intake duct and secure it properly.

4. Replace Fuel Filter (if applicable)

Locate the fuel filter; it may be under the vehicle or in the engine compartment.
Release fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines and remove the old filter.
Install the new fuel filter, ensuring the arrows on the filter align with the fuel flow direction.
Reconnect the fuel lines and reinstall the fuel pump fuse.
