Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical issues during repairs.

2. Replace Air Filter

Open the hood and locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the old air filter and inspect the housing for dirt.
Install the new air filter, ensuring it fits snugly.
Re-secure the air filter housing.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Spray throttle body cleaner onto a clean cloth or directly onto the throttle body.
Use a soft brush if necessary to remove carbon buildup.
Open the throttle plate manually to clean the inner surfaces.
Reattach the intake duct securely.

4. Replace Spark Plugs (if necessary)

Locate the ignition coils on top of the engine.
Remove the bolts or clips securing the ignition coils and disconnect the electrical connectors.
Carefully pull out the ignition coils and set them aside.
Use a spark plug socket to remove the old spark plugs.
Install new spark plugs, ensuring they are gapped correctly (typically 0.044 inches for this model).
Reinstall the ignition coils and secure them in place.

5. Check Fuel System

Reconnect the battery and turn the ignition to the "On" position without starting the engine to pressurize the fuel system.
Use a fuel pressure gauge to check if the pressure meets specifications (typically between 30-50 PSI).
If pressure is low, consider replacing the fuel pump or checking for clogged fuel filters.
