Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace the Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and visually inspect it for dirt and obstructions.
Replace the air filter if it is dirty or clogged.
Reassemble the air filter housing.

3. Clean the Throttle Body

Remove the throttle body by disconnecting the electrical connector and unscrewing the mounting bolts.
Use throttle body cleaner and a soft cloth to clean the interior surfaces.
Reinstall the throttle body and reconnect the electrical connector.

4. Check and Replace Spark Plugs and Coils

Remove the ignition coil cover if applicable.
Disconnect the ignition coils and unscrew them from the cylinder head.
Remove the old spark plugs using a spark plug socket and inspect them for wear.
Replace with new spark plugs and reinstall the ignition coils.

5. Test and Replace Fuel Pump or Filter (if necessary)

Connect a fuel pressure gauge to the fuel rail to check the pressure.
If the pressure is low, inspect and replace the fuel filter and/or fuel pump as needed.
Reconnect everything securely.
