Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery to avoid any electrical shorts during repairs.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the existing air filter; inspect it for dirt and damage.
Replace with a new air filter if contaminated.
Reassemble the air filter housing and secure it.

3. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter, typically situated along the fuel line.
Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines using a fuel line disconnect tool.
Remove and replace the old fuel filter with a new one.
Reconnect the fuel lines and reinsert the fuel pump fuse.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft cloth to clean the throttle plate and housing.
Ensure the throttle plate moves freely without obstruction.
Reattach the intake duct securely.

5. Inspect and Replace Spark Plugs

Remove the ignition coils by unbolting them and disconnecting the electrical connectors.
Unscrew the spark plugs using a spark plug socket.
Inspect the spark plugs for wear or fouling; replace if necessary with OEM specifications.
Reinstall the ignition coils and reconnect the electrical connectors.

6. Test Drive

Reconnect the battery.
Start the engine and allow it to idle.
Test drive the vehicle to assess the improvement in acceleration.
