Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Replace Air Filter

Locate the air filter housing, usually at the front of the engine compartment.
Open the housing by unclipping or unscrewing it.
Remove the old air filter and clean the housing with a damp cloth.
Install the new air filter, ensuring it fits snugly in place.
Reassemble the housing and secure it.

3. Clean Throttle Body

Remove the intake duct leading to the throttle body by loosening the clamps.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Open the throttle plate manually to clean both sides.
Reinstall the intake duct and ensure all clamps are tightened.

4. Replace Spark Plugs

Remove the ignition coils by unbolting them.
Disconnect the electrical connectors from the coils.
Using a socket set, remove the old spark plugs from their respective cylinders.
Gap the new spark plugs according to specifications and install them.
Reattach the ignition coils and connectors.

5. Inspect Fuel System

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "On" position without starting to check the pressure reading.
If the pressure is below specifications, check the fuel pump and filter for issues.
Replace the fuel filter if necessary and ensure proper fuel pump operation.
